Pin puppet-lint to ~> 1.0 series.

We can't upgrade beyond 1.0 series without either dropping tests using
puppet-lint-filerserver-check, or waiting for the author of that Gem to
merge in a fix for the dependencies:
https://github.com/camptocamp/puppet-lint-fileserver-check/pull/2

To avoid breaking tests of this module meanwhile, we shall pin.
