increase lower bounds for stdlib, vcsrepo

Closes #326.

Hello @kenyon,

I'm not sure puppet/puppetboard is compatible with puppet/python >= 6 as we still find virtualenv and manage_virtualenv_package in the init file.
If you look at the changelog of puppet/python, we can see that these parameters are no longer present:

• Drop python::virtualenv defined resource from changelog
• no more reference to virtual in the init file 6.0.0+
• explanation on why virtualenv is now deprecated in the PR

Also, I tested with your PR and that's what I'm getting (with mod 'puppet/python', :latest in our Puppetfile) :

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement, Class[Python]:
  has no parameter named 'virtualenv'
  has no parameter named 'manage_virtualenv_package' (file: /.../production/modules/puppetboard/manifests/init.pp, line: 188, column: 5) on node puppet...

Here, I see two solutions for that (I'm not a puppet expert, maybe I wrong but I try to add some ideas):

• dropping virtualenv parameters for systems having puppet/python >= 6.0.0
• use python::pyvenv described here which is already present in puppet/python >= 4.1.0

Indeed, I did not look for such incompatibilities. I figured we could find and fix those in other pull requests. So if you could submit a PR that would be great. 👍

Don't know why travis times out trying to download the puppetdb module. Maybe it needs puppetlabs/puppetlabs-puppetdb#327

After review of the differences which where part of #317, it seems two lower bounds where not included and if applicable, we can update this PR to fix this.
