[bug#72265] [PATCH 0/1] Fix hardware acceleration support for librewolf

[Nikita Domnitskii]

Current approach with LD_LIBRARY_PATH seems wrong for multiple reasons:
1. It doesn't work
2. It would require us to add all available drivers and every shared
library that drivers load

Currently it works like that:

--8<---------------cut here---------------start------------->8---
$ MOZ_SANDBOX_LOGGING=1 librewolf
libva info: Trying to open /run/current-system/profile/lib/dri/iHD_drv_video.so
[3323] Sandbox: SandboxBroker: denied op=open rflags=2000000 perms=0 
path=/gnu/store/371amhgyc25i0frgxkllp94v6rvvyl0y-intel-media-driver-nonfree-24.1.5/lib/dri/iHD_drv_video.so
 for pid=3971
[3971] Sandbox: Failed errno -13 op open flags 02000000 path 
/run/current-system/profile/lib/dri/iHD_drv_video.so
[3323] Sandbox: SandboxBroker: denied op=access rflags=0 perms=0 
path=/gnu/store/371amhgyc25i0frgxkllp94v6rvvyl0y-intel-media-driver-nonfree-24.1.5/lib/dri/iHD_drv_video.so
 for pid=3971
[3971] Sandbox: Failed errno -13 op access flags 00 path 
/run/current-system/profile/lib/dri/iHD_drv_video.so
libva info: va_openDriver() returns -1
--8<---------------cut here---------------end--------------->8---

If I'll add /run/current-system/profile/lib/dri to LD_LIBRARY_PATH it
tries to load gmmlib:

--8<---------------cut here---------------start------------->8---
$ MOZ_SANDBOX_LOGGING=1 
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/run/current-system/profile/lib librewolf
libva info: Trying to open /run/current-system/profile/lib/dri/iHD_drv_video.so

failed: libigdgmm.so.12: cannot open shared object file: No such file or 
directory
libva info: va_openDriver() returns -1
--8<---------------cut here---------------end--------------->8---

So I propose to use NixOS approach (already upstreamed)
