specs-go/config.go: Make Root.Readonly omitempty

wking · wking · commit f307cfc93975 · 2016-05-06T22:16:10.000-07:00
It's an optional setting, and this change will fix the wordy:

  $ ocitools generate --template &lt;(echo '{}')
  $ grep readonly config.json
      "readonly": false,

Instead, config.json will not contain a 'readonly' entry at all.
