QEMU_CAPS_MACH_VIRT_GIC_VERSION is always asserted for VIR_ARCH_AARCH64.

Note that this patch is a direct conversion of the logic originally
residing in the capabilities code. A better coversion would be (based on
whether it is available for just AARCH64 or also ARM) to base it on the

4ee4809907 qemu: validate: Fix logic for validating presence of the HPET timer
Commit 24cc9cda82 switched over to use -machine hpet, but one of the
steps it did was to clear the QEMU_CAPS_NO_HPET capability.

The validation check still uses the old capability though which means
that for configs which would explicitly enable HPET we'd report an error.

Since HPET is an x86(_64) platform specific device, convert the
validation check to an architecture check as all supported qemu versions
actually support it.

Modify a test case to request HPET to catch posible future problems.
