Greetings,

I was trying to build an x86_64 binary on an aarch64 machine, and noticed that
`qemu-binfmt-service-type' was missing the x86_64 platform definition.

* gnu/services/virtualization.scm (%x86_64): Add variable.
(%qemu-platforms) Add it.

This sounds reasonable to me, I haven't checked the exact values are
correct but I'm assuming they're sensible.

Pushed to master as 9ad311ec15c05efc78f74252e7eb6cddfb0b5cea.

Thanks,

Chris
