Fix default accelerator when configured with --disable-kvm

The default accelerator is hardcoded to 'kvm'. This is a fine
default for qemu-kvm normally, but if the user built with
./configure --disable-kvm, then the resulting binaries will
not work by default

* vl.c: Default to 'tcg' unless CONFIG_KVM is defined
