security: remove security_sb_post_mountroot hook
The security_sb_post_mountroot() hook is long-since obsolete, and is
fundamentally broken: it is never invoked if someone uses initramfs.
This is particularly damaging, because the existence of this hook has
been used as motivation for not using initramfs.
Stephen Smalley confirmed on 2007-07-19 that this hook was originally
used by SELinux but can now be safely removed:
