Make access to deadline_timer thread-safe
According to boost doucmentation shared deadline_timers are not
thread-safe. Adding a mutext to protect access to
boost::asio::deadline_timer instance in Swift::BoostTimer.
This fixes a data-race reported by TSAN when running
Swiften/QA/ClientTest/ClientTest.
Test-Information:
Verified that the data-race report is gone with this fix.
