Bug 24693: Move GD from recommends to requires in cpanfile

Without it, catalogue/detail.pl dies (and probably other scripts too)

Test plan:
1. Uninstall GD, reload starman
2. Go to catalogue/detail.pl. Confirm that it dies
3. Reinstall GD, reload starman
4. Go to catalogue/detail.pl. Confirm that it work normally

catalogue/detail.pl dies without GD.
Seems correct switch to require
No errors

It does not die for me, it dies if I enable LocalCoverImages, then try to upload an image.

Maybe we should clarify what does *required* mean for us.

Personally I believe that every Perl module that we directly `use` or `require` without checking its presence should be flagged as required. Even if the require is behind a syspref check or something like that. Put more simply, if Koha dies because of a missing Perl module, that module is a required dependency.

Maybe later we can build something based on cpanfile's `feature` (https://metacpan.org/pod/distribution/Module-CPANfile/lib/cpanfile.pod#feature) to warn when an optional feature is enabled and the required modules for this feature are missing.

The whole 'feature' stuff from the cpanfile move came up earlier that I was expecting.. but I suspected it would raise it's head at some point.

I'm really not sure what way to fall on this one.. I don't like that changing a syspref can completely 'break', i.e lead to a die, koha.. but at the same time if a set of functionality is optional, the dependencies it requires really aught to be too.

That was wrong, I removed libgd-perl, that removed koha-common. The alias restart_all got broken, as it did not correctly restart plack, etc.

So yes, detail.pl crashes with GD.

We will make it (really) optional if there is a real need for that.
