nextcloud-native, nextcloud-native-git: new packages

Source package built from the release tag and a VCS package following
main, both from :ui:createDistributable - the same jpackage application
image that nextcloud-native-bin repackages from upstream's .deb.

nextcloud-native-git is not version-tracked: its pkgver comes from
pkgver() at build time, so latest_version() reports the snapshot already
in the PKGBUILD and the update run stays a no-op until the packaging
itself changes.
