Update search.cpan.org URLs

search.cpan.org has (sadly) been gone for several years now.  This patch
updates the remaining important instances of that URL found in the parts
of the core distribution under the control of Perl 5 Porters, i.e.,
excluding the cpan/ directory.

The patch does not attempt to update URLs in "historical" data, e.g.,
older perldeltas.  Nor does it attempt to deal with results produced by
Porting/checkURL.pl.

Following discussion: Abandon changes to 'if' and 'PathTools' META.json
files.
