m4/groff.m4: Fix Savannah #65762.
* m4/groff.m4 (GROFF_WCOREFLAG): Use `AC_LANG_PROGRAM` more
idiomatically; stop explicitly defining `main()`. Reportedly resolves
implicit function declaration warnings from Clang.
Fixes <https://savannah.gnu.org/bugs/?65762>. Thanks to Eli Schwartz
for the report.
