Statically link benchmark test binaries.

After update to Go 1.20 in 5572ab2f7d ("Bump go version to 1.20"), the
benchmark jobs have been failing on BuildKite. This seems to be happening
because benchmark test binaries are built in Docker containers but are run on
the host. On some hosts, the glibc isn't compatible with glibc in our docker
container. So dynamically linked binaries may fail. Linking them statically
resolves this glibc compatibility issue.

As a result, this change also adds support for static test binaries to
tools/bazeldefs/go.bzl.
