This change solve two issue:
1) Policies related to recovery should be only included in recovery
policy
2) In CM trees the sepolicy dir was always bootable/recovery-
twrp/sepolicy, even if recovery path was bootable/recovery

This patch set should make it easier to build TWRP in non-Omni
trees as it allows TWRP to modify the sepolicy instead of having
to merge a patch in external/sepolicy to meet TWRP's needs.
