Add what we need to allow composd to run and expose an AIDL service.
Also delete the policy for compsvc; we never access it in the host
now, and the real policy is in microdroid. Retain the compos_exec
type, since it is referenced in the APEX sepolicy.

Test: adb shell cmd -w android.system.composd; no denials.

It's a test tool which is generally run as root, and will be deleted
eventually. It doesn't need its own label; system_file works fine.
We never actually allowed it anything, nor defined a transition into
the domain.
