Set pg_setting.pending_restart when pertinent config lines are removed

This changes the behavior of examining the pg_file_settings view after
changing a config option that requires restart.  The user needs to know
that any change of such options does not take effect until a restart,
and this worked correctly if the line is edited without removing it.
However, for the case where the line is removed altogether, the flag
doesn't get set, because a flag was only set in set_config_option, but
that's not called for lines removed.  Repair.
