linux-firmware: Remove unlicensed firmware

Browse Source 
Create a new REMOVE_UNLICENSED variable and do_install() logic to
allow for marking certain firmware files as something to remove and not
package up.

This comes from the fact that the WHENCE file has a number of firmware
entries that have no license information or very questionable
declarations as to what the license is for the firmware.
