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

The existing device package and its dependencies are for i9305, but
renaming them to i9300 makes more sense, as the i9300 is the base
version (SIII) and the i9305 (SIII LTE) is the improved version.
