libmythtv: Use the actual MythPlayer pause state

Remove the pause member variable from PlayerContext and access the pause
state of the player directly. Fixes some inconsistencies in the pause
state and another step along the long road of removing PlayerContext
entirely.

Pimped from master 8c18a32

Closes #9665
