motif: Combine status details into a single flags member.

The timer_tick, view_goal_on_game and use_ewmh_icons values all are used
to encode just a single bit of information.  We can combine them into
a single member to reduce the overall size of the state structure.

Dropping the timer ID further enables a slight reorganization of the
timer process which seems to reduce the overall code size somewhat.
