Bug 19067: Map clubs/ into INTRANET_CGI_DIR in Makefile.PL

This patch adds the required entry in Makefile.PL so the clubs/ dir is correctly installed
during the make install step.

To test:
- Run:
  $ cd kohaclone
  $ perl Makefile.PL
- Follow any install method and options
- Run
  $ make
  $ ls blib/INTRANET_CGI_DIR/ | grep clubs
=> FAIL: No clubs dir
- Run:
  $ make clean
- Apply this patch
- Run:
   $ perl Makefile.PL
- Follow any install method and options
- Run
  $ make
  $ ls blib/INTRANET_CGI_DIR/ | grep clubs
=> SUCCESS: The clubs/ dir is correctly picked for inclussion in the intranet cgi dir
- Sign off :-D
