Fix eavesdropping config to avoid masking bad dbus configs
Fix eavesdropping config to avoid masking bad dbus configs

BUG=chromium-os:26824
TEST=repro'd chromium-os:26790 on a test system with this config,
demonstrating that it no longer masks the bug. Confirmed
dbus-monitoring still works while doing so. (Tested with
help from jorgelo.) Confirmed the 26790 fix is not regressed by this
either.
