Subject: [PATCH] Add initial installboot(8) tests

For now they all run on softraid(4) on vnd(4) and do not require any
setup up-front, making it easy to spot bugs in MD code.

amd64 passes, sparc64 passes with the exception of "-r/mnt" usage,
as is done by the installer, when the softraid volume contains
more than one chunk.  arm64 needs more love, still.

Will be hooked up per-arch soon.

OK anton
