mesa: update 20.1.8 -> 20.2.1

Build tweaks:
- drop separate dri option and the patch that adds it; just setting -Ddri-drivers='' is enough
- strip leading/trailing commas from drivers' lists, as upstream no longer allows blank entries if the list
is not empty (e.g. -Ddri-drivers=,driver1,driver2 is now producing an error).
- drop the long-obsolete llvm 3.3/3.2 logic
