This solves two problems:
1. Using the host /tmp directly meant that concurrent tests could
collide attempting to use the same file, and that misbehaving tests
never have their /tmp output cleaned up.
2. Host /tmp is not world-accessible on all hosts. Some tests (e.g.,
sticky) access files in /tmp from other users, so we need to ensure
that its /tmp is world-accessible.

This change adds support for the SO_BROADCAST socket option in gVisor Netstack.
This support includes getsockopt()/setsockopt() functionality for both UDP and
TCP endpoints (the latter being a NOOP), dispatching broadcast messages up and
down the stack, and route finding/creation for broadcast packets. Finally, a
suite of tests have been implemented, exercising this functionality through the
Linux syscall API.

- Use new user namespace for namespace creation checks.
- Ensure userns is never nil since it's used by other namespaces.

In addition to simplifying the implementation, this fixes two bugs:
- seqfile.NewSeqFile unconditionally creates an inode with mode 0444,
but {uid,gid}_map have mode 0644.
- idMapSeqFile.Write implements fs.FileOperations.Write ... but it
doesn't implement any other fs.FileOperations methods and is never
used as fs.FileOperations. idMapSeqFile.GetFile() =>
seqfile.SeqFile.GetFile() uses seqfile.seqFileOperations instead,
which rejects all writes.

Multiple tests were creating the same directory before removing it, making it
possible for concurrent tests to fail because the directory already exists.

stdout can be (and, in automated testing, often is) a host pipe or
similar resource shared between multiple parallel tests, such that it
can become transiently full during testing.

The implementation of O_CLOEXEC is orthogonal to every property tested
by these tests; removing it significantly reduces the number of
redundant tests we run.
Also remove no-op calls to VecCat (calls with a single argument).

Otherwise, C++11-compliant compilers may select PosixErrorOr(const T&)
as the relevant constructor, and fail because std::vector<Mapping> is
not copyable (because Mapping is not copyable).
This is a C++11 defect that is fixed in C++14 (and in C++11 mode for
Clang, but not GCC). See DR 1579,
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1579.

Runsc wants to mount /tmp using internal tmpfs implementation for
performance. However, it risks hiding files that may exist under
/tmp in case it's present in the container. Now, it only mounts
over /tmp iff:
- /tmp was not explicitly asked to be mounted
- /tmp is empty
If any of this is not true, then /tmp maps to the container's
image /tmp.
Note: checkpoint doesn't have sentry FS mounted to check if /tmp
is empty. It simply looks for explicit mounts right now.
