The commit 78ff64081949 ("vfs: Convert tracefs to use the new mount API")
broke the gid setting when set by fstab or other mount utility.
It is ignored when it is set. Fix the code so that it recognises the
option again and will honor the settings on mount at boot up.
Update the internal documentation and create a selftest to make sure
it doesn't break again in the future.
