gnulib-tool: correctly detect absence of m4 directories

$m4dirs is incorrectly counting.  In my particular case
(correct value: 0, detected value: 1), this resulted in gnulib-tool
silently exitting with no visible error (and no job done).

* gnulib-tool: Avoid extra newline on data passed to wc -l.
