QEmu normally install BIOS images under `/usr/local` prefix, but
Homebrew installs them under `/opt/homebrew`. This change searches both
locations and then puts back to an unpathed name if it doesn't find the
BIOS. (I imitated other architectures' implemenations in that failback
behavior.)

Cause qemu to fall back to using TCG acceleration when HVP acceleration
is not available on Darwin Aarch64. Qemu prints a warning which it is
desirable to leave to embarrass the upstream Qemu into approving the HVF
patches.
