autodetect: allow whitelisting by MODULE_FS_ALIAS
Linux 3.9 adds a filesystem alias in the supporting module in the form
of fs-$filesystem. While this is mainly aimed at security/paranoia, it
does mean that we can make better use of the fact that we always resolve
filesystem as aliases to filesystem modules. Do an additional lookup in
add_if_avail to resolve the new alias in addition to the filesystem
name itself.
