m4/groff.m4: Migrate `AC_FOREACH` -> `m4_foreach`.
* m4/groff.m4 (GROFF_CHECK_GROHTML_PROGRAMS): Migrate from `AC_FOREACH`
to `m4_foreach` to avoid obsolescence warning from GNU Autoconf 2.70
or later.
Fixes <https://savannah.gnu.org/bugs/?61059>. Thanks to Bjarni Ingi
Gislason for the report.
Also make code style more readable.
