lineage-iosched: restorecon scheduler tuneables before touching them

Browse Source 
* LineageOS/android_system_sepolicy@0e3235f45d removed open, read,
  and write for init to general sysfs types. As schedulers are
  changed, the related directories gets dynamically torn-down and
  rebuilt, but they lacks proper contexts. We need to make sure the
  context is correct before init can write to these nodes.
