linux: Add fsconfig

It was added on Linux 5.2 (ecdab150fddb42fe6a739335257949220033b782) as a way to a configure filesystem creation context and trigger actions upon it, to be used in conjunction with fsopen, fspick and fsmount. The fsconfig_command commands are currently only defined as an enum, so they can't be checked on tst-mount-consts.py with current test support. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
