file_context: explicitly label all file context files
file_context files need to be explicitly labeled as they are now split
across system and vendor and won't have the generic world readable
'system_file' label.
Bug: 36002414
Test: no new 'file_context' denials at boot complete on sailfish
Test: successfully booted into recovery without denials and sideloaded
OTA update.
Test: ./cts-tradefed run singleCommand cts --skip-device-info \
--skip-preconditions --skip-connectivity-check --abi \
arm64-v8a --module CtsSecurityHostTestCases -t \
android.security.cts.SELinuxHostTest#testAospFileContexts
