Compile the utility `service` on host as `aservice`

... and run it.

It is not named `service` on host to avoid collision
with service(8).

fds don't work yet because of b/185909244.

Test: aservice list
      # doesn't work well because of Java support b/190450693 and
      # single-threaded service support b/191059588
Test: aservice call manager 4 i32 15
      # listServices
Test: aservice call manager 7 s16 android.hardware.light.ILights/default
