Update Dockerfile & build script and add /etc/nsswitch.conf:

- Add nsswitch.conf to configure LibC Name Service inside the container
- Change my email in the Dockerfile
- Update build script to install software as a `build-deps` virtual package so that adding a package to it will be automatically	removed at the end of the build script
