sepolicy-legacy: Restore fm radio permissions for system_app

Commit I40a4f68eb8ded948d44653d3bc0209bbb3d9ef35 removed these
permissions because the QCOM FM2 app was relabelled as platform_app
which made these rules unnecessary, but there are also device which
use the AOSP FMRadio app which was not relabelled.

Restore the permissions to allow the FMRadio app to function properly
again.
