Libvirt would also benefit from screendump to fd:name (where name refers
to an fd passed via getfd).

You will need a separate option for this, if you add fd:name parsing,
since name won't necessarily have a .png suffix (I guess libvirt could
use getfd to name an fd with a .png suffix, but that seems weird).
