linux-firmware: add iwlwifi-misc package for remaining iwlwifi firmware
Package all remaining iwlwifi firmwares that are not individually
packaged into a single package. This is distinct from the virtual
linux-firmware-iwlwifi package so that the -misc firmwares can be
installed without pulling in all other firmwares via dependencies.
