[meta-networking][PATCH v5 2/3] wireless-regdb: Add wireless-regdb-static package with static regulatory data

[Krzysztof Kozlowski <krzk@kernel.org>]

Small embedded systems might:
1. Want to get rid of daemons as much as possible (therefore be built
   without CRDA),
2. Not receive user-space incremental updates but an entire system
   upgrade (with kernel).

Linux kernel since v4.15 allows loading static regulatory data from
/lib/firmware/regulatory.db.

Add additional package to wireless-regdb recipe which provides such
static data.
