Fix Ubuntu 24.04 system dependencies

- Replace obsolete libgl1-mesa-glx with libgl1-mesa-dri for Ubuntu 24.04
- Add fallback mechanism to handle both Ubuntu 22.04 and 24.04 package names
- Update condition from startsWith(matrix.os, 'ubuntu') to runner.os == 'Linux'
- Add libgcc-s1 for better compatibility

Fixes: Package 'libgl1-mesa-glx' has no installation candidate error
