perf, ui: Eliminate stack-smashing protection compiler complaint

Browse Source 
The gcc complains about small auto-var strings being allocated from stack space.
Make them const to avoid this:

 | CC util/ui/util.o
 | cc1: warnings being treated as errors
 | util/ui/util.c: In function ‘ui__dialog_yesno’:
 | util/ui/util.c:108: error: not protecting function: no buffer at least 8 bytes long
 | make: *** [util/ui/util.o] Error 1

The real bug is in the newtWinChoice() ABI - but that's an
externality we cannot fix here, so we use this workaround.
