    Handle huge /bin directories in libdb2 test
    
    The test suite for libdb2 uses /bin as a source of filenames and
    contents for insertion into databases.  Fedora 17 (and possibly other
    OSes) have /bin symlinked to /usr/bin, which can vastly increase the
    number of files found, exceeding some limits of the test databases.
    Truncate this list of files at 100 to prevent this problem.
