input/libinput: only reset supported options

This adds checks to the input_manager_libinput_reset_* functions to
only attempt resetting supported options on reload. This should have no
functional difference to the user, but will remove several `Failed to
apply libinput config: Unsupported configuration option` lines from the
log that can be noisy and potential red herrings.
