update_engine: Migrate time-based glib main loop calls to MessageLoop.
This patch replaces most calls to g_idle_add* and g_timeout_add* with
the equivalent MessageLoop::Post*Task(). To maintain compatibility with
unittests running the main loop and doing I/O we instantiate a
GlibMessageLoop for those tests.
BUG=chromium:499886
TEST=unittests still pass.
