file_analysis/Manager: Remove RunState.h include

The file_analysis/Manager.h header only needs run_state::terminating, so
declare just that similar to what Val.h does. This breaks ZBody compilation
due to OP_READING_LIVE_TRAFFIC_V and OP_READING_TRACES_V accessing
run-state::reading_live and run_state::reading_traces. Add the include to
ZBody.cc as a fix.

This may break external plugins, too, but then they didn't have the
right includes setup to begin with.
