verbatim: reserve enough space for the result also in non-UTF-8 locales 

Also when each character is just one byte, parse_verbatim_kbinput()
can produce two bytes; plus the terminating NUL that is three bytes.

This fixes https://savannah.gnu.org/bugs/?58959.

Bug existed since version 4.9, commit 03d296eb.
