FP3: Add dummy perf profile

Since lineageos 15.1 the power hal doesn't use the

perf_lock_use_profile() method anymore.

It was used to apply performance profiles.

On startup the perfd daemon is looking for at least

one profile which is used as default.

So there is only a perf-profiles0.conf to make the

daemon happy.

Removes log spam:
