Subject: [PATCH] init: Resolve kernel trace_marker permissions on post-fs

 * The permissions were not set to 222 instead of 220,
    thus introducing regular logs from libcutils:
    "cutils-trace: Error opening trace file: Permission denied (13)"

 * Refers to frameworks/native/cmds/atrace/atrace.rc
