This is an artifcat of how domaincapstest does stuff:

'fillQemuCaps' has:

if (fillStringValues(&loader->values,
                     "/usr/share/AAVMF/AAVMF_CODE.fd",
                     "/usr/share/AAVMF/AAVMF32_CODE.fd",
                     "/usr/share/OVMF/OVMF_CODE.fd",
                     NULL) < 0)

So the output files have this fake data without any consideration.

Arguably it would be a better idea to simply fill this with obviously
fake strings.
