autotest (network): add test for multiple shill instances
Test that shill aborts if another instance of shill is already
running. shill should abort in such cases, to prevent two instances
from battling over how to configure the network interfaces.
BUG=chromium:356874
TEST=manual
Manual test: ran this before and after the shill change in
CL:195012. The test failed before the change, and passed afterwards.
