geninfo: Change json module

Perl module JSON may not be present on all distributions. Switch to
using JSON:PP instead which is a Perl core module since Perl 5.14.0.

xref: https://perldoc.perl.org/5.14.0/index-modules-J.html

Note: JSON:PP is included in packages named perl-JSON-PP or
libjson-pp-perl on some distributions
