/dev/hw_random is accessed only by init and by EntropyMixer (which
runs inside system_server). Other domains are denied access because
apps/services should be obtaining randomness from the Linux RNG.

Otherwise it defaults to the label of /data/system and
cannot be distinguished from any other socket in that directory.
Also adds allow rule required for pre-existing wpa_socket transition
to function without unconfined_domain.

This CL completes the renaming of domain system to system_server by
removing the "system" typealias that was temporarily added to avoid
breaking the build while the rename CLs are landing.

This is a follow-up CL to the extraction of "system_app" domain
from the "system" domain which left the "system" domain encompassing
just the system_server.

Since this change cannot be made atomically across different
repositories, it temporarily adds a typealias "server" pointing to
"system_server". Once all other repositories have been switched to
"system_server", this alias will be removed.
