gnu: Add dependency on Perl's 'Module::Build' as needed.

'Module::Build' was deprecated in Perl 5.20 and removed in 5.22.
Some packages need to explicitly depend on it now.

* gnu/packages/perl.scm (perl-class-factory-util):
(perl-date-manip, perl-devel-checkbin): Add 'native-inputs' field.
(perl-module-build)[description]: Mention that it used to be in Perl.
* gnu/packages/web.scm (perl-cgi-simple)[native-inputs]: Add
PERL-MODULE-BUILD.
