Updates documented linux dependencies (#414)

* Updates documented linux dependencies

Previously our linux development dependencies where listed in the
building.md documentation on our bootstrap-ubuntu.sh file. In order to
minimize duplication, the documentation now points to
bootstrap-ubuntu.sh

* Linux dependencies documentation now only points to script

* Update docs/building.md
