shill: cleanups and logging

Fix a few small issues I noticed while working on suspend-resume
issues with PPP dongles, and add some logging that helps understand
the suspend/resume process.

More specifically:
- Add some override annotations to cellular.h
- Fix a typo in device.h
- Update a stale comment in device.h
- Add some logging for termination actions. This uses scope Manager
  for HookTable. It's conceivable that some other component will
  use HookTable as well. But let's worry about that when it happens.
- Remove obsolete headers (FRIEND_TEST_ALL_PREFIXES)
- Add comment for Cellular::ModemState

BUG=None
TEST=unit tests
