This CL adds hand-written SELinux rules to:
- define the boringssl_self_test security domain
- label the corresponding files at type boringssl_self_test_marker
and boringssl_self_test_exec.
- define an automatic transition from init to boringssl_self_test
domains, plus appropriate access permissions.
Bug: 137267623
Test: When run together with the other changes from draft CL topic
http://aosp/q/topic:bug137267623_bsslselftest, check that:
- both /dev/boringssl/selftest/* marker files are
present after the device boots.
- Test: after the boringssl_self_test{32,64} binaries have
run, no further SELinux denials occur for processes
trying to write the marker file.
