This reverts commit c778945806.
I believe this is exactly what brings the staging branch into
the right shape after the last merge from master (through staging-next);
otherwise part of staging changes would be lost
(due to being already reachable from master but reverted).
Announcements:

I've rebased the patches accordingly and avoided:
meson.build:320: WARNING: Platform `surfaceless` is now always selected; setting this option will be an error in Mesa 20.3
meson.build:324: WARNING: Platform `drm` is now automatically selected; setting this option will be an error in Mesa 20.3
This will also fix the list in the configuration summary:
EGL/Vulkan/VL platforms: x11 surfaceless wayland drm surfaceless drm

Optimistically drop disk cache patch, changelog mentions related
changes to cache behavior.
Not sure if those changes address our problem
(can we count on build-id?) so someone more familiar with
this should probably take a look before merging :).
Mesa usually uses the timestamps of the llvm and driver shared libraries
as a cache key. In /nix/store these are all zero, so we'll include
$(drivers) in the cache key, which should be unique for all combinations
of mesa and llvm versions.
