no writing to system_file_type is the intention here, but they only restricted system_file. this does not touch the untrusted_app lock neverallow, because it's specific to a single system_file, and r_file_perms includes 'lock'. Bug: 281877578 Test: build (neverallow only change) Change-Id: I6c6078bc27c49e5a88862eaa330638f442dba9ee
