Bug#681894: [checks/debhelper] please bump PEDANTIC_COMPAT to 8

[Jakub Wilk <jwilk@debian.org>]

Package: lintian
Version: 2.5.10
Severity: wishlist

lenny has been archived and squeeze ships with debhelper 8.0.0. It means 
that we can:
- bump PEDANTIC_COMPAT to 8;
- downgrade debhelper-overrides-need-versioned-build-depends severity to 
pedantic.
