Add a script based on the "menagerie-fuzz" buildbot test. Running

"./tools/fuzz-test.sh /path/to/capture/files/*" will iterate over the
specified capture files, using editcap to introduce errors and tethereal
to check for bugs.  It will do this until tethereal exits abnormally or
a dissector bug is encountered.
