kvm-unit-tests: only enable for ARM on Cortex-A{7,12,15,17}

Browse Source 
The library uses the hypervisor instruction HVC, which is only
available on ARMv7-A with Hypervisor extensions. This is limited to
Cortex-A{7,12,15,17}.

In addition the build unconditionally passes -marm so it also needs
ARM instructions to be available, but that is already implied by the
CPU selection.

Implicitly fixes

though it is still not clear why ld doesn't accept the -Ttext=...
option there.
