[PATCH for 7.0 5/5] bsd-user-smoke: Add to build

[Warner Losh]

Add a simple bsd-user smoke test for ensuring bsd-user is minimally
functional. This runs only when bsd-user has been configured. It adds a
simple execution of 'hello world' type binaries for bsd-user. At the
present these are tiny, hand-crafted binaries that are statically linked
and do not depend on any host libraries being present (they also take
advantage of the fact that on FreeBSD all system call numbers are
uniform on all architectures). This was done both for building and
testing simplicity, as well as recognizing the current state of bsd-user
in qemu upstream is extremely basic.
