PR241491: bin/ps: use locale-based string specifiers

[yuripv]

Summary

Use %hs instead of %s in bin/ps for it to correctly output locale specific date/time (at least).

Test Plan

Compare output of LC_ALL=uk_UA.UTF-8 ps -o lstart and LC_ALL=uk_UA.KOI8-U ps -o lstart | iconv -f koi8-u. Also reproducer from the PR.

Looks great! Thanks....

The "%hs" bits look good, but why do you add the call to xo_no_setlocale()?

Thanks,
Phil
