domain_deprecated is a private attribute, which means that none of
its rules will be copied to vendor policy.  Unfortunately, this
means that any public type that used the attribute now loses policy
rules on which a vendor may have been relying unknowingly.  Add the
domain back in the compatiblity file so that O vendor policy remains
sufficient.

This was marked deprecated in 2014 and removed in 2015, let's remove
the sepolicy now too.

Add /dev/kmsg_debug on userdebug devices, to allow crash_dump to log

commit: 5c6a227e added the oc-dev
sepolicy prebuilts (api 26.0), but did not include the corresponding
base mapping file, which is to be maintained along with current
platform development in order to ensure backwards compatibility.

Bug: 37896931
Test: none, this just copies the old mapping file to prebuilts.
Change-Id: Ia5c36ddab036352845878178fa9c6a9d649d238f

Copy the final system sepolicy from oc-dev to its prebuilt dir
corresponding to its version (26.0) so that we can uprev policy and
start maintaining compatibility files, as well as use it for CTS
tests targeting future platforms.

Bug: 37896931
Test: none, this just copies the old policy.
