Bug#567092: libcgi-fast-perl: incomplete upstream version dependency

[Niko Tyni]

Package: libcgi-fast-perl
Version: 5.10.1-9

Now that CGI/Fast.pm is in the core directory again, we need to
ensure that future upgrades to 5.10.2 or 5.12.0 will force upgrading
libcgi-fast-perl too.

I suppose we need to use something like

 Package: libcgi-fast-perl
 Depends: perl (>= ${source:Version}), perl (<< 5.10.2~)

or better calculate a substvar for the next version in 
debian/rules like we do for ${Upstream-Version}.

Alternatively the next version of perl-base could have a
 Breaks: libcgi-fast-perl (<< xxx)
but I think the first way is slightly cleaner as it keeps the
libcgi-fast-perl dependencies self-contained.
