Robert Helgesson 7ca412a2fa nix-generate-from-cpan: fix core module detection
This makes the detection of core modules a bit more robust by checking
the module inclusion in a pure Perl interpreter. This ensures that any
extra path in the `nix-generate-from-cpan` script's `PERL5LIB` does not
affect the generated package expression.
