Bug 12393 - Depend on SSL module for LWP, for OverDrive

The OverDrive integration needs to connect to an authentication server
over HTTPS, and many systems do not install the necessary module
(LWP::Protocol::https) by default.

Test plan (for patch):
  1) Run koha_perl_deps.pl -a, verify that LWP::Protocol::https appears in
     listing.

Test plan (to verify that LWP::Protocol::https is necessary, needs OverDrive access):
  1) Remove LWP::Protocol::https (liblwp-protocol-https-perl under Debian).
  2) Run an OverDrive search on the OPAC, it should fail.
  3) Reinstall LWP::Protocol::https.
  4) Rerun OverDrive search, it should now succeed.

Note: older versions of Debian do not need to install LWP::Protocol::https separately;
the Debian scripts have been updated to reflect this divide.
