shill: Use TaskEnvironment for EventDispatcherForTest

Currently, EventDispatcherForTest initializes a SingleThreadTaskExecutor
internally while the latter is not intended for test usage, according to
its comment. This patch changes to use base::test::TaskEnvironment,
which gives us opportunities to have a better unit test, e.g., easy to
test PostDelayedTask().

Also modifies DeviceInfoTest according to this change.

This change will not affect other unit tests.
