Audio HAL server needs to set SCHED_FIFO scheduling policy
for its threads that communicate with FastMixer threads of
AudioFlinger that use the same scheduler.

auditallow (added in commit 758e6b36)
has been in place for about 2 weeks now, and no hits. Remove
execute_no_trans.

The net effect of this change is that priv_apps won't be able to exec()
a file from their home directory, but dlopen() and friends will still
work.

Test: Compiles and boots successfully.
Test: No auditallow messages received via SELinux denial collection.

Prevent sepolicy and sepolicy.recover from showing up in the root
filesystem when they will not be created as part of it.  Also make
sure both are added as dependencies to version_policy to ensure the
neverallow checks are run.

And do some clean up:
Replace LOCAL_TARGET_ARCH with global arch specifier that won't get
clobbered, clean up sepolicy.recovery's eng specification, ensure that
build macros are applied across all policy generation, not just
plat_policy, and make sure that all private variables are cleared and
alphabetized at the end.

Angler.

(cherry picked from commit 32cacb42)

healthd is being split into 'charger' and 'healthd' processes, that
will never run together. 'charger' is to be run only in charge-only
and recovery, while healthd runs with Android.

While they both share much of battery monitoring code, they both now
have reduced scope. E.g. 'charger', doesn't need to use binder anymore
and healthd doesn't need to do charging ui animation. So, amend the
SEPolicy for healthd to reduce it's scope and add a new one for charger.

Test: Tested all modes {recovery, charger-only, android} with new policy

other people's data.
