qemu: do not use domain virt type to get default version

We do not need VIR_DOMAIN_VIRT_QEMU to get qemu default
version. With the 'os_type' and 'arch'in capabilities,
we could identify 'emulator' which is enough to get the version.

Actually VIR_DOMAIN_VIRT_QEMU is not the only domain virt type for
qemu driver, there are VIR_DOMAIN_VIRT_KVM and VIR_DOMAIN_VIRT_HVF.
If TCG is disabled in qemu, it will cause the error that could not
find suitable emulater when access version.
