Update Pod-Usage to CPAN version 1.64

  [DELTA]

1.64 (marekr)
- CPAN#93170: Abstract in pod doesn't follow convention
    fixed the NAME section
- CPAN#86932: documentation does not work with use strict
    rewritten parts of the DESCRIPTION section
- CPAN#86776: "pod2usage -verbose 2 FILE" is broken when perldoc is missing
    verified that pod2usage acts decently if perldoc is missing
    note: a Perl installation without perldoc is like a haunted house
    without ghosts
