add platform.Memd tast-test

This test checks that memd is running and responding to
events of interest by creating clip files.

The events of interest are faked.  A tab discard is simulated
by sending a D-Bus message that looks as if it came from Chrome.
A kernel OOM kill is simulated by producing a syslog line that
is recognized by the anomaly_collector daemon.  Thus this also
tests the OOM-kill reporting functionality of the anomaly collector.

BUG= chromium:900291 
TEST=ran the test
