Add workarounds for Honor devices

Browse source 
Audio did not work on Honor devices.

To make it work, a system context must be set as a base context of
FakeContext (so that a PackageManager is available), and a current
Application and ActivityThread must be set.

These workarounds must not be applied for all devices, because they
might cause other issues.

Fixes #4015 <https://github.com/Genymobile/scrcpy/issues/4015>
Refs #3085 <https://github.com/Genymobile/scrcpy/issues/3805>
