[fusl] Add llvm's lit tool to third_party

This will be used for running libcxx's tests on top of fusl.

This code is a directory in upstream llvm. It is also a PyPi
package: https://pypi.python.org/pypi/lit. It's not particularly easy to
consume in domokit as either of those things, though. Since it doesn't
change upstream much at all, let's just check in a copy.

This was taken from llvm revision 250162. It is exactly the contents of
the //utils/lit directory, plus the LICENSE.TXT file.

We might want to put lit directly under //third_party if we're going to be using
this for other libraries (e.g. any LLVM projects).
