run: Unset EGL driver paths

Similar to how b8d8d80 inhibited passthrough of environment variables pointing the Vulkan loader towards a specific ICD, do the same for the EGL paths used by libglvnd to discover the GL driver to use, as well as for NVIDIA's EGLStream shim. These paths are typically referencing the host filesystem; if the user is referencing paths only available in the sandbox, they can use --env or overrides for them.
