Subject: [PATCH] Add lz4 dependency to the build instructions (#1308)

* Add lz4 dependency to the build instructions

At build-time of exosphere, the `split_program.py` script is called.
It requires python module `lz4` -> https://github.com/Atmosphere-NX/Atmosphere/blob/master/exosphere/program/split_program.py

Adding lz4 to the building.md documentation.

* Remove "(Python Library)" from deps-entries
