Revert "CHROMIUM: Remove node name from introspection files"

This reverts commit 52fbe37e5d78011366eec0033d5374a0c8950f0e.

Instead of modifying those introspection XMLs directly in the
modemmanager-next git repository, we now patch them in the
modemmanager-next ebuild instead (CL:427389).

BUG=chromium:680751
CQ-DEPEND=CL:427389
TEST=Tested the following:
1. Build modemmanager-next and shill with CL:427389 applied.
2. Verify that the root <node> in the introspection XML of each
   ModemManager object interface (i.e.
   /usr/share/dbus-1/interfaces/org.freedesktop.ModemManager1.*.xml)
   doesn't have the name="/" attribute.
