gpgme: ensure manpage generation is deterministic

gpgme: ensure manpage generation is deterministic

In a similar way to the previous commits with pod2man, gpgme will not
generate manpages on a clean build but will on rebuilds due to
do_package -> rpm-native -> ... -> libgpg-error-native, where the
libgpg-error-native recipe provides the yat2m tool.

To ensure that we generate manpages deterministicly, depend on this
recipe.
