net/wifi-firmware-kmod: stop building kmods on main and 14.2 and on

In Feb 2024 a feature to firmware(9) was introduced to be able to load
plain firmware files (not kernel modules) from /boot/firmware/ .
If the system is modern enough stop building kernel modules but simply
copy the firmware files in.
This makes the entire build process a lot simpler.
For older versions we still have to generate kernel modules (though
they all shipped with firmware in src so we can possibly unsupport
them in the future).
