selinux: add security in-core xattr support for tracefs
Since kernel 4.1 ftrace is supported as a new separate filesystem. It gets automatically mounted by the kernel under the old path /sys/kernel/debug/tracing. Because it lives now on a separate filesystem SELinux needs to be updated to also support setting SELinux labels on tracefs inodes. This is required for compatibility in Android when moving to Linux 4.1 or newer.
