switch to the full 40 character GPG fingerprint for apt keys

[sjahl]

This commit replaces the 8-character apt key value with the full 40 character one (I noticed this was producing a warning when used with puppetlabs-apt 1.8.0 and puppet 3.8.1). I saw other references to the short GPG fingerprint for Suse, but left them as-is, since I think the long key is really only required for puppetlabs-apt.

This should fix #36

Test fails seems completely unrelated.

Jenkins standing by to test this. If you aren't a maintainer, you can ignore this comment. Someone with commit access, please review this and clear it for Jenkins to run; then say 'jenkins, test it'.

You need to modify the Gemfile and some .travis.yml to pass the tests.
I suggest you to have a look to my PR #60 .

[sjahl]

If #60 gets merged, I'm happy to rebase this patch on it.
