Security/VFS: re-export security_inode_permission symbol

Unionfs needs it because it has to do everything in there, but skip the
EROFS test (so copyup can be triggered).  There's no easy way to execute
parts of security_inode_permission() without copying  and duplicating much
of its functionality, so exporting the symbol seems the simplest.
