qemu - ship ovmf vars for x86_64 and aarm64 (#40719)

the shipped 60-edk2-aarch64.json and 60-edk2-x86_64.json files do
correctly state that
 * edk2-i386-vars.fd is the nvram-template for x86_64
 * edk2-arm-vars.fd is the nvram-template for aarch64

But that was not clear to me as a consumer and I expected x86_64 vars
file to be available.

This is wasteful of disk space, but more clear.
