We want both chagallwifi and chagalllte to be able to depend on
firmware-samsung-chagall, for both their downstream and mainline
kernel variants.
Previously we used install_if like:
install_if="device-samsung-chagallwifi-kernel-mainline"
which will only work for chagallwifi and not chagalllte. Instead we
add two nonfree subpackages to the device packages that install_if's
depending on kernel choice.
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.
Fixes: #718
