include/package-pack: drop version from provides

Adding a version to the provides causes it to conflict with other
packages that provides the same package, further details are available
here: https://gitlab.alpinelinux.org/alpine/apk-tools/-/blob/master/doc/apk-package.5.scd#L199

This was intitally done, if I remember correctly, to support depending
on the specific kernel modules. Due to patches to APK, versions
containing hashes work now, too, so this is no longer required.

Only add the version to packages that define an ABI version since other
packages depend against the package name plus ABI version.

While at it, format the now rather complex call.
