Bug 7063: add available perl packages for Debian in install_misc/debian.packages

Bug 7063: add available perl packages for Debian in install_misc/debian.packages

Takes work done by Eduardo Trápani, alphabetizes, and adds two other packages:

libuniversal-require-perl
libgravatar-url-perl

From my testing, only CGI::Session::Driver::memcached remains missing; it is only
packaged for sid and wheezy at this time
