Thibault Jamet d9697e275e Split go build in Dockerfile
To maximize the usage of cache, split the govendor get in steps:
- govendor fetch to get the pinned versions of dependencies
- go install to actually build the binary

Doing so allows not to re-download the whole dependencies when changing
lines in hugo repository

The current Dockerfile generates an image of 16.6MB
