universal7870: selinux: fix first call no audio

I was not able to set:

> allow system_suspend hal_audio_default:binder transfer;

as hal_audio_default is part of vendor which is not avail in private
but system_suspend is part of private and not avail in vendor.

this commit fixes the first call on boot issue until I find a better
way fixing that. without this the very first call will loose audio after
some seconds while subsequent calls work fine.

log:
