Update test configuration documentation

Remove the old tests/data/README documentation and move the note
about krb5.conf into tests/config/README.  (This should change later
to use tests/config for that file.)  Add a license statement to that
file.  Create an empty tests/config directory in the build tree if
the build directory is not the source directory.
