Updated p5-CPAN to 2.1600.

2017-02-14  k  <andk@cpan.org>

* release 2.16

* four weeks after the TRIAL2 release cpantesters have produced
392 pass and 5 fail; by my estimation the fails are two bugs in
the test suite: (1) insufficient rubustness against make -j and
(2) insufficient robustness against missing unzip program; both
will be targeted at a later date

* otherwise no functional change; only changes in the distroprefs/
directory (which is not used per default) and minor changes to
Makefile.PL and t/97*.t
