Up until now we have only formatted non-default GIC versions on

QEMU versions, where the option is available. Moreover, having
the GIC version formatted on the command line at all times
ensures that QEMU changing its own defaults doesn't affect the
ABI of libvirt guests.
A few test cases are removed to avoid extra churn. It doesn't
matter for coverage, as those scenarios are already covered by
other parts of the test suite.
This patch is better viewed with 'git show -w'.

And because of code in qemuDomainDefEnableDefaultFeatures related to TCG
and GIC and (it seems) bz1414081, the default for TCG would then be v2,
hence the reason for the none-tcg change, if I'm reading correctly at
least... Although perhaps not obvious just reading this patch ;-)
