kojivmd: pass "-F qcow2" to qemu-img create

Browse source 
In RHEL 9 (qemu-img-6.2.0-11.el9_0.3), the "qemu-img create" command
requires the "-F" flag that specifies the second image's format.

qemu-img-1.5.3-175.el7_9.6 recognizes this -F flag also, so it should be
safe to use on all supported platforms.
