Libguestfs - Mar 2014 - [PATCH] tests: add simple automake to junit xml conversion script

Add (and ship) a simple ocaml script which can convert the results of
automake unit tests (.trs + .log files) to a junit-like .xml file,
suitable for importing in CI systems (such as jenkins).

If you want, you can turn this into a regular script.  Put the
following at the top of the file:

  #!/usr/bin/ocamlrun ocaml

and make sure the file is executable.

ACK anyway.
