When running nvidia-ctk on a system that uses a custom XDG_DATA_DIRS
environment variable value, the configuration files for `glvnd`,
`vulkan`, and `egl` fail to get passed through from the host to the
container. Reading from XDG_DATA_DIRS instead of hardcoding the default
value allows for finding said files so they can be mounted in the
container.

This change adds a driver root abstraction that defines how
libraries are located relative to the root. This allows for
this driver root to be constructed once and passed to discovery
code.
