locale.5, repertoiremap.5: clarify keyword syntax

Hi Michael,

All the glibc locale/repertoiremap files use the format described in the patch below, the fix is trivial (and adds an example just in case), I presume these were copypasted from charmaps.5 page, all the glibc charmaps use slightly different format for keywords (I'll send a separate patch to address charmaps.5 next).
