FC4 perl module upgrades/cleanups

[Warren Togami]

FC4test2 freeze is coming real soon, so most of these perl spec changes 
will not happen until after it unfreezes in order to avoid the risk of 
breaking deps.  I will however try to upgrade CPAN module versions 
before the freeze without changing deps.

Chip Turner just mentioned that he wants to fix up cpanflute2 to just 
auto-re-generate all these specs.  So it may be best to discuss the 
implementation details of this rather than dozens of manual changes to 
packages.  Wait until Chip chimes in on this thread.
