Missing dependencies for perl module DateTime-Locale

[ken@…]

Some time between DateTime::Locale-1.12 and -1.16 it acquired the usual shedload of extra build and test dependencies.

To build: File::ShareDir::Install which needs

Module::Build::Tiny

which needs ExtUtils-Config, ExtUtils-Helpers, and ExtUtils-InstallPaths

To test: File::ShareDir which needs Class::Inspector and Test::File::ShareDir which needs

Class:Tiny File::Copy::Recursive Path::Tiny Scope::Guard as well as Test::Fatal

When this and #9324 are completed, the versions as at Sunday 4th June of the perl modules used by biber will be working and tested with perl-5.26.0.

Also, with perl-5.26.0 the version of List::Util (Scalar::List::Utils) is adequate, but for people using perl-5.24.1 that needs to remain, so explain that.
