Make puppet work with Ubuntu Vivid

The repo for Vivid on apt.puppetlabs.com only contains a 'PC1' repo
instead of 'main', also only binary packages and no source. So skip
installing this repo completely for now until we find out which
packages are really needed from it.

Package emacs23-nox is replaced by emacs24-nox.
