Bug 24217: use Modern::Perl for modules when strict is missing

Bug 24217: use Modern::Perl for modules when strict is missing

We absolutely need that for modules.
We are enabling strict by using Modern::Perl.
Note that other modules from C4 use strict and warnings, instead of
Modern::Perl

Test plan: git grep 2505 **/*.pm should not return any results

And let's see later what needs to be fixed.
