[runtime tests] go language test enhancement

- Unexported some passing tests. This will increase the testing surface and
  will be especially helpful when this is enabled for vfs2.
- Run tool tests with -v (verbose output). We only print the output when a test
  fails so this should not clutter the output.
- Run tool tests with "-no-rebuild" flag.
- Surround test name with appropriate regex, i.e. ^testname$. This will ensure
  that only that test is run. Earlier running go_test:os would also run
  go_test:os/exec, go_test:os/signal, go_test:os/user. This should help speed
  up the tests as we do not run the same test multiple times anymore.
- Updated bugs.

Updates #3191
