Dpkg::Source::Package: Auto-convert binary signatures to OpenPGP ASCII Armor

When we are building a source package, if we find a binary signature in
the form of a .sig file, we should try to auto-convert it to the format
that we expect to include in the source package, which is an OpenPGP
ASCII Armor.
