If current LOCALE not UTF-8, national encoding in "ps" output broken.

For example, mplayer with cyrillic args (filename in KOI8-R) not present in "COMMAND" column.

Bug in bin/ps/ps.c:

Function xo_emit requires an argument %s in UTF-8 only encoding. But acceptably
replace %s with %hs, in which case pass argument in $LANG encoding.
