distro/rhel84: build qcow2 images with compat=0.10

Browse source 
By default, `qemu-img convert` creates qcow2 images usable in qemu 1.1 and
newer. RHEL 8 guest images are meant to be bootable on RHEL 6 though.
Unfortunately, RHEL 6 has qemu 0.12, therefore these images cannot be used
there.

To fix this, we need to use the new qcow2_compat option in qemu assembler
to override the default compat version and make qcow2 images that can be used
in qemu 0.10 and newer.

For this, we need osbuild 28 that isn't yet available in of any of
downstreams, therefore we need to pin it everywhere.

# RHEL 8.4: qcow2 images can now be used by older QEMUs
Previously, the guest image for RHEL 8.4 was only usable by QEMU 1.1 and
newer. However, this image should be usable on RHEL 6 that ships an older
version of QEMU. This is now fixed and the guest image can be now used by
QEMU 0.10 and newer.
