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).

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
The effective change is that "drirc.d/00-mesa-defaults.conf" will now be
installed to $out instead of $drivers and not appear under
"/run/opengl-driver/share/" anymore.
This is done to fix#89421, i.e. so that Mesa will find and load the
included DriConf defaults. The other files in "$drivers/share" will not
be moved to $out as some Nixpkgs logic might depend on them being
available under "/run/opengl-driver/share/" (e.g. addOpenGLRunpath).
Overriding it just for .drivers had the advantage of limiting rebuilds,
but it seems less clean and apparently it can interact a bit surprisingly
with some other overrides. /cc #94444.
Also this will get removed once patchelf gets updated.
Without this, the radv cache uuid would fall back to using the
timestamps of the radv and llvm shared libraries, which are fixed in
/nix/store. This caused cache collisons, which resulted in crashes
(e.g. #92807).
Quoting from the splitString docstring:
NOTE: this function is not performant and should never be used.
This replaces trivial uses of splitString for splitting version
strings with the (potentially builtin) splitVersion.
