Add pmb:cross-native/!tracedeps to applicable firmware packages and
secure both with a test.
This sets the pmb:cross-native and !tracedeps options on all firmware-*
packages that are compatible with the native compilation method. A unit
test ensures the presence of both options while maintaining a list of
exempted packages.
