fsmonitor: fix exception message scraping

pywatchman.CommandError formats its error message such that
'unable to resolve root' is not a prefix. This change fixes that by
instead just searching for it as a substring.

    try:
        print(f, '->', os.readlink(f))
    except OSError as err:

            raise
        print(f, '->', f, 'not a symlink')
