CrOS: Populate WiMAX status to chrome://system via debugd.

This CL adds a binding in DebugDaemonClient to invoke debugd's
GetWiMaxStatus DBus method and modifies DebugDaemonLogSource to gather
WiMAX information via GetWiMaxStatus.

BUG=chrome-os-partner:21256
TEST=Verify that chrome://system shows correct information under
'wimax-status' on Chromebook with / without a WiMAX module.
