Increase the memory limit for qemu-img
We appear to be bumping up against this limit when deploying
RHCOS images(currently 977MB). Curiously the problem isn't
happening all the time but increasing the limit eliminates it.
This limit was intruduced to guard against a malicious image
allocating an arbitrary amount of memory. Nothing else runs
on hosts when IPA is running so we should be ok bumping up
the limit.
