[BUG] Conflict of version for DRI driver

[NicsTr]

Describe the bug

When launching any application using mesa from alacritty, I get the following error message: DRI driver not from this Mesa build ('23.2.1-1ubuntu3.1~22.04.2' vs '24.0.5-1ubuntu1').

When I install alacritty through cargo install alacritty everything works as expected.

To Reproduce

Steps to reproduce the behavior:

1. Install alacritty from snap (snap install alacritty --classic)
2. Launch an alacritty terminal
3. Run glxinfo from this terminal
4. See error

Expected behavior

No error should occur.

Environment (please complete the following information):

• OS: Ubuntu 24.04
• Alacritty Version: 0.13.2
• Graphics Cards: AMD Ryzen 7 7840U w/ Radeon 780M Graphics

The same error comes in Ubuntu 23.10 with output:
libGL error: DRI driver not from this Mesa build ('23.2.1-1ubuntu3.1~22.04.2' vs '23.2.1-1ubuntu3.1')

Also reported in #27
I've found by accident that the command would run with sudo, and normally in the "system" terminal.
After digging a bit, I found that LIBGL_DRIVERS_PATH and LIBVA_DRIVERS_PATH was set to the "snap" path (/snap/alacritty/ ...), so I just reset it inline when running glxgears (or any app that needs it).
I'm largely unfamiliar to snap packaging, but I hope it helps to fix this.

[Gooygeek]

I can confirm these environment variables are to blame.
By unsetting them or by setting them to the system installation, gui apps (e.g. glxgears) can be launched.

I've added the following to my .zshrc:

export LIBGL_DRIVERS_PATH="/usr/lib/x86_64-linux-gnu/dri"
export LIBVA_DRIVERS_PATH="/usr/lib/x86_64-linux-gnu/dri"
