Go's dev.typeparams branch already claims to be Go 1.18, so our !go1.18 build
tags breaking testing gVisor with that branch.
Normally I would not want to bump the build tags this early, but I plan to
extend checklinkname to check the assumptions in these files and remove the
build tags ASAP. So we just go ahead and bump the tags until then to unblock
testing.

This CL introduces a 'checklinkname' analyzer, which provides rudimentary
type-checking that verifies that function signatures on the local and remote
sides of //go:linkname directives match expected values.
If the Go standard library changes the definitions of any of these function,
checklinkname will flag the change as a finding, providing an error informing
the gVisor team to adapt to the upstream changes. This allows us to eliminate
the majority of gVisor's forward-looking negative build tags, as we can catch
mismatches in testing [1].
The remaining forward-looking negative build tags are covering shared struct
definitions, which I hope to add to checklinkname in a future CL.
[1] Of course, semantics/requirements can change without the signature
changing, so we still must be careful, but this covers the common case.

These are bumped to allow early testing of Go 1.17. Use will be audited closer
to the 1.17 release.

This enables pre-release testing with 1.16. The intention is to replace these
with a nogo check before the next release.

None of the dependencies have changed in 1.15. It may be possible to simplify
some of the wrappers in rawfile following 1.13, but that can come in a later
change.

Currently there are no ABI changes. We should check again closer to release.
