qemu: x86_64 is good enough for i686

Browse Source 
virt-manager on Fedora sets up i686 hosts with "/usr/bin/qemu-kvm" emulator,
which in turn unconditionally execs qemu-system-x86_64 querying capabilities
then fails:

Error launching details: invalid argument: architecture from emulator 'x86_64' doesn't match given architecture 'i686'
