Remove outdated sepolicies

Browse Source 
* Support deodexed ROM: This should not be done and dexpreopt is mandatory since P
   Xposed: Xposed handles them just fine, at least in the latest version 89.3
   suMiscL6: For whatever audio mods, a leftover of phh time
   Liveboot and suBackL6: Was for CF.lumen and LiveBoot, not needed now

 * Also cleanup binder sepolicies since we allow all binder transactions.
