wireless-regdb: Add recipe

Since wpa-supplicant is provided,
the database of permitted frequencies should also be provided.

wireless-regdb-static should be used with kernel >= 4.15.
wireless-regdb can be used with older kernels and is mostly
irrelevant here, but keeping it in meta-networking would
create needless recipe duplication.

This package was previously in meta-networking.
