New type for printk_formats, allow traced_probes.

Test: ls -lZ /sys/kernel/tracing/printk_formats
      [...] u:object_r:debugfs_tracing_printk_formats:s0 [...]

Test: setenforce 0;
      runcon u:r:system_server:s0 cat /sys/kernel/tracing/printk_formats
      logcat complains about /sys/kernel/tracing/printk_formats

Test: setenforce 0;
      runcon u:r:traced_probes:s0 cat /sys/kernel/tracing/printk_formats
      logcat does not complain about /sys/kernel/tracing/printk_formats

(need to setenforce 0, because otherwise the exec of ls is denied).
