Bug#1005184: lintian: package-does-not-install-examples should not look in tests

[Scott Kitterman <debian@kitterman.com>]

Package: lintian
Version: 2.114.0
Severity: minor

Currently on lintian.d.o the package-does-not-install-examples test is
triggered for python-tomlkit because of files in [tests/examples/].
These aren't, in fact, examples for tomlkit, they are examples of TOML
files used in the tests.

I think that generally this test shouldn't look in test directories.

Filed as minor since this is a pedantic test, but I think it should be
improved, particularly since it shows up on lintian.d.o.
