Change --qemu-smp default from 2 to 1

When trying to a boot a centos epel VM using QEMU, it will hang during
boot if the qemu smp option is set to a number higher than 1. To avoid
this and similar issues, let's default to 1 core per VM. If users need
more they can always configure the option explicitly.
