selftests/ftrace: Fix to use remount when testing mount GID option

Browse Source 
Fix mount_options.tc to use remount option to mount the tracefs.
Since the current implementation does not umount the tracefs,
this test always fails because of -EBUSY error.
Using remount option will allow us to change the mount option.
