PGP::Sign 1.03

Part of the continuing saga to clean up CPAN testing failures with this module. Test reports uncovered a tighter version dependency for the flags I was using for GnuPG v2 (2.1.23) and a version dependency for GnuPG v1 (1.4.20). As with the previous release, I'm now skipping tests if the version is too old, since this makes the CPAN test results more useful to me.

I also took advantage of this release to push the Debian packaging to Salsa (and the upstream branch as well since it's easier) and update the package metadata, as well as add an upstream metadata file since interest in that in Debian appears to have picked up again.

You can get the latest release from CPAN or from the PGP::Sign distribution page.
