systemd: add recipe for systemd-repart-native 257.6

Add a recipe to build systemd-repart-native.
The chosen version is a relatively recent one, to support:

1) PKCS#11 uris [1] to pass in the private key when creating a
discoverable disk image (as·--private-key-source).

2) setting Compression=/CompressionLevel= in the configuration [2],
which is then passed over to a (recent version of) mkfs.erofs

The recipe was adapted from an incomplete 'systemd-tools' patch [3]
that is floating upstream.
