txr: fix inappropriate "takes no argument".

txr is reporting "option --<foo> takes no argument"
for any unknown option <foo>, which is silly.

* txr.c (no_dbg_support): Drop setuid privilege here
before doing the output.
(txr_main): Block that diagnoses "takes no argument"
is now reachable only by goto. Every no-argument option tests
the org variable and branches there if there are arguments.
Some rearrangement of drop_privilege() calls and
insertion of missing ones via it now being called in
no_dbug_support.
