This change fixes several issues with the fsgofer host UDS support. Notably, it
adds support for SOCK_SEQPACKET and SOCK_DGRAM sockets [1]. It also fixes
unsafe use of unet.Socket, which could cause a panic if Socket.FD is called
when err != nil, and calls to Socket.FD with nothing to prevent the garbage
collector from destroying and closing the socket.
A set of tests is added to exercise host UDS access. This required extracting
most of the syscall test runner into a library that can be used by custom
tests.
Updates #235
Updates #1003
[1] N.B. SOCK_DGRAM sockets are likely not particularly useful, as a server can
only reply to a client that binds first. We don't allow bind, so these are
unlikely to be used.

The simple test script has gotten out of control. Shard this script into
different pieces and attempt to impose order on overall test structure. This
change helps lay some of the foundations for future improvements.
* The runsc/test directories are moved into just test/.
* The runsc/test/testutil package is split into logical pieces.
* The scripts/ directory contains new top-level targets.
* Each test is now responsible for building targets it requires.
* The install functionality is moved into `runsc` itself for simplicity.
* The existing kokoro run_tests.sh file now just calls all (can be split).
After this change is merged, I will create multiple distinct workflows for
Kokoro, one for each of the scripts currently targeted by `run_tests.sh` today,
which should dramatically reduce the time-to-run for the Kokoro tests, and
provides a better foundation for further improvements to the infrastructure.

In cl/264434674 and cl/264498919, we stop running test cases
in parallel to not overload test hosts. But now tests requires
more time to run, so we need to increase a default number of
shards or a default test timeout. Let's start with increasing
the number of shards and see how it will works.

bazel runs a few instances of syscall_test_runner in parallel
and then syscall_test_runner runs test cases in parallel. It might
be a reason why we see that test hosts are overloaded and sandboxes
start slowly. It should be better to control how many tests are
running in parallel from one place, so let's try to disable this
feature in syscall_test_runner.

When run in parallel, multicast packets can be received by the wrong test. The
tests in the target are run in an isolated network namespace, but if
parallelism is enabled, multiple tests from the same target will run in
parallel within the target's network namespace. Disabling parallelism only
allows one test to run in the network namespace at a time, which prevents
interaction.

To do so, we must add the ability to add tags to the syscall tests.

Lots of tests use /tmp for the tests. Force /tmp to be
mounted over fsgofer instead of tmpfs.

Instead just find the syscall_test_runner binary in the shell script.
