src/roff/groff/pipeline.c: Use strsignal().
POSIX.1-2008 added strsignal() to the C library and recommended its use
over sys_siglist[], but groff's pipeline management hadn't been updated
in that respect since that time.
* configure.ac: Check for strsignal().
* src/roff/groff/pipeline.c (xstrsignal): Use return value of
strsignal() if it is available.
Thanks to an anonymous contributor for the report and the patch.
Fixes <https://savannah.gnu.org/bugs/?59835>.
