Add F6 test emulation

Likely your change looked similar to this patch. You need to:

1. Apply the patch
2. Rebuild vmm.ko
3. Rebuild bhyve

I'm guessing you did #1 and #2. The instruction emulation runs in the bhyve
user process which needs #3.

Note: I tested this with a fabricated test in a FreeBSD VM with a user prog=
ram
and it seemed to work. I'd be curious if this fixes your uefi issue.
