[fetchmail][PATCH] Missing files in po/POTFILES.in

All source files which contain translatable strings are supposed to
be listed in po/POTFILES.in. Recently some new source files have
been added to fetchmail without updating po/POTFILES.in, meaning
that the strings from these files will be missing in new built pot
and po files.

The attached patch will bring POTFILES.in up to date.
