ci,linux: Support Patreon releases

The Early Access AppImage needs to be accessible through liftinstall, so
a couple modifications need to made:

The DIR_NAME needs to not include the revision info.
The EA AppImage name cannot contain revision info.
The EA AppImage has to be packaged with the rest of the yuzu package,
which means both binaries and the source are bundled with it now in an
archive.

In addition, fix the source archive so yuzu can actually be built from
it.

upload: Copy AppImage to both mainline and EA release package
