From: Sergei Trofimovich <slyfox@gentoo.org>

Before the change /usr/share/qemu/firmware/50-edk2-x86_64-secure.json
contained the relative path:
            "filename": "share/qemu/edk2-x86_64-secure-code.fd",
            "filename": "share/qemu/edk2-i386-vars.fd",

After then change the paths are absolute:
            "filename": "/usr/share/qemu/edk2-x86_64-secure-code.fd",
            "filename": "/usr/share/qemu/edk2-i386-vars.fd",

The regression appeared in qemu-5.2.0 (seems to be related
to meson port).
