Subject: [PATCH] Fix non-deterministic failures on newer perls

The hash randomization changes in the Perl 5.17 series
made perl.req to occasionally fail to report the dependencies.

Improved diagnostics report

 Use of each() on hash after insertion without resetting hash
 iterator results in undefined behavior, Perl interpreter: 0x9e7010 at
 /home/niko/tmp/libb-perlreq-perl-0.82/blib/lib/B/Walker.pm line 122.

so use keys() instead of each(), as suggested by perldiag.pod.
