Here are some modifications I made to Pierre's code:

- Removed \overriding InstrumentName.padding and opted instead for 
self-alignment-X of RIGHT.
- Kept the stencil for SystemStartSquare but applied an extra-offset to 
slide it underneath the instrument name for the StaffGroup.
- To prevent the other brackets from being shifted, I also had to adjust 
SystemStartSquare's direction to RIGHT.
- Changed InstrumentName's layer to be top-most.
- Used the OrchestraGroup's instrumentName with \markup \whiteout...
