x86/selftests, x86/vm86: Improve entry_from_vm86 selftest
The entry_from_vm86 selftest was very weak. Improve it: test
more types of kernel entries from vm86 mode and test them more
carefully.
While we're at it, try to improve behavior on non-SEP CPUs. The
old code was buggy because I misunderstood the intended
semantics of #UD in vm86, so I didn't handle a possible signal.
