Build script for a hermetic build of xfstests

["Ted Ts'o" <tytso@xxxxxxx>]

With the six patches which I just sent (3 for xfsprogs, 3 for
xfstests), I'm now able to build xfstests hermetically using the
following script.  It's still a bit rough, but I offer it up if anyone
else wants to be able to build xfstests without having to worry about
hidden dependencies in the distro-supplied /usr/include/xfs
directories, etc.
