Make fstest work out-of-the-box on Solaris:

- Solaris' setgroups(2) doesn't change process' effective gid, so set it
  explicitly.
- POSIX doesn't define O_NOFOLLOW. FreeBSD returns EMLINK when target is
  a symbolic link, but Solaris returns ELOOP then.
- Solaris doesn't define O_SHLOCK and O_EXLOCK flags.
