fix `githubrepo` hook for groups repositories remotes

when there was a repository per group we could not use the hook
for pushing since we only had **one** remote configured. This PR
configures each repository its own remote based in the `groups`
config, as follows:

```
---
groups:
  first:
    remote_repo: git@gitlab.lab:oxidized/first.git
  second:
    remote_repo: git@gitlab.lab:oxidized/second.git
```
