[libvirt] [PATCH V2] AArch64: Porting of armv7l conditons to run qemu for aarch64.

AArch64 qemu has similar behavior as armv7l, like use of mmio etc.
This patch adds similar bypass checks what we have for armv7l to aarch64.
E.g. we are enabling mmio transport for Nicdev.
Making addDefaultUSB and addDefaultMemballoon to false etc.
This patch also adds testcase to qemuxml2argvtest as suggested
during review comments of V1 of same patch.
