Update metadata.json to not give dependency errors in puppet3.8

[cryptk]

On puppet3.8 there are dependency errors listed due to the use of hyphens rather than forward slashes in the metadata.json file:

root@testbox:/etc/puppet/modules/hiera# puppet module list
Warning: Missing dependency 'puppetlabs-inifile':
  'hunner-hiera' (v2.0.1) requires 'puppetlabs-inifile' (>= 1.0.0 < 2.0.0)
Warning: Missing dependency 'puppetlabs-stdlib':
  'hunner-hiera' (v2.0.1) requires 'puppetlabs-stdlib' (>= 4.3.1 < 5.0.0)
/etc/puppet/modules
├── hunner-hiera (v2.0.1)
├── puppetlabs-inifile (v1.5.0)
└── puppetlabs-stdlib (v4.12.0)

Altering the hyphens to forward slashes resolves this:

root@stackstorm:/etc/puppet/modules/hiera# puppet module list
/etc/puppet/modules
├── hunner-hiera (v2.0.1)
├── puppetlabs-inifile (v1.5.0)
└── puppetlabs-stdlib (v4.12.0)

I know that you guys like to have tests for fixes, but I am unsure how to write a test for problems such as this one...

Hey,

we're currently doing a modulesync in #143. This should fix the current errors in travis. Please rebase after #143 is merged, than I can merge your PR. No tests needed for this change.
