When testing with a HVF-only binary, we get:
3/12 qemu:func-quick+func-aarch64 / func-aarch64-version
ERROR 0.29s exit status 1
stderr:

Output: qemu-system-aarch64: No accelerator selected and no default
accelerator available
Fix by checking for HVF in configure_accelerators() and using
it by default when no other accelerator is available.
