IMPALA-7024: Convert Coordinator::wait_lock_ to SpinLock

For consistency with the other locks in this class, use
SpinLock rather than boost::mutex. We expect SpinLock to
work okay for locks that block since it is adaptive.

This came up in the code review for IMPALA-5384, but I
wanted to make this change separately, just in case of
unforseen side-effects.
