Bug#373668: linitan: [source-contains-CVS-dir] enhance lintian-info description

[Jari Aalto <jari.aalto@cante.net>]

Package: lintian
Version: 1.23.21
Severity: wishlist

lintian-info for source-contains-CVS-dir reads

    N:
    N:   Package contains a CVS directory. It was most likely included by
    N:   accident, since transient CVS data usually doesn't belong in packages.
    N:   Export from CVS rather than use a checkout.

The problem is not necessarily due to directly packaging from CVS, but
that the upstream tarball contains CVS directories in it.

Please enhance the message by referring to also check
variable debhelper::DH_ALWAYS_EXCLUDE in those cases
