vm86 exposes an interesting attack surface against the entry
code. Since vm86 is mostly useless anyway if mmap_min_addr != 0,
just turn it off in that case.
There are some reports that vbetool can work despite setting
mmap_min_addr to zero. This shouldn't break that use case,
as CAP_SYS_RAWIO already overrides mmap_min_addr.
