[perl #119359] perlvar/Errno contradict each other about %!

I wonder.

Currently programmer doesn't have to list Errno.pm in prerequirements
(prereqs in CPAN meta), and doesn't have to care about vendors who
decouple Perl core modules from core. It just works.

And if we explicitly document relation between Errno and %!, will above
still be true?
