Backport of r49037
Some parts of this package were named rt73-pci-firmware before which
looks like a copy and past error. This renames all parts to rt73-usb-
firmware and then the firmware gets build and the dependencies from the
package with the kernel module are also working correctly.
This fixes#22069
