please version-build-depend on qemu

[Christian Ehrhardt ]

Hi,
while test backporting edk2 I found an odd breakage.

It just spills OUT: b'' to the console forever.

Some debugging revealed that it is actually the qemu that is too old.

For this section of d/rules

113 debian/ovmf-install/OVMF_VARS.ms.fd: debian/UefiShell.iso debian/oem-string-vendor
114 »···python3 $(OVMF_VARS_GENERATOR) --qemu-binary /usr/bin/qemu-system-x86_64 \

You will need at least qemu commit

     smbios: support setting OEM strings table

That appeared in v2.12.0-rc4

So maybe a b-dep with version on 2.12 ?
 qemu-system-x86 (>= 1:2.12+dfsg-1)

Not too critical but as discussed on chat probably still worth to add on the next upload
