  Optimize Docker image build to minimize its size

Combine apt-get related commands in a single RUN statements,
to prevent some additional but useless layers created during the build.

Size difference:
```
$ docker images
REPOSITORY TAG    IMAGE ID CREATED         SIZE
after      <none> 84cac1   9 minutes ago   629 MB
before     <none> ff3e9b   32 minutes ago  651.5 MB
```
