clock - re-add to distribution (Perl modules now available)

[Jari Aalto]

cloc (count lines of code) was removed because the needed
Perl modules were not yet in Cygwin.

    1.55 UPDATED https://cygwin.com/ml/cygwin-announce/2012-02/msg00047.html
    1.55 RM      https://cygwin.com/ml/cygwin-announce/2012-02/msg00060.html

Cygwin now bundles the required Perl modules:

    Algorithm::Diff
    Regexp::Common

I have 1.60 ready for upload. It can now be relisted in:

  https://cygwin.com/cygwin-pkg-maint
  and in !packages file
