Capture stderr when we run composd_cmd

Errors are written to stderr, but on failure we only log stdout, so we
can't tell what the problem is.

This is only one instance of this - there are others in ComposTestCase
and AVFHostTestCase - but this is the one causing me problems right
now. I'll do the others in a following CL.
