Add workarounds for Honor devices

Audio did not work on Honor devices.

Two workarounds are necessary:
 - a system context must be set as a base context of FakeContext (so
   that a PackageManager is available),
 - the same workaround as for Meizu phones must also be applied (so that
   ActivityThread.currentApplication() return a valid instance).

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

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