This change attempts to load the nvidia, nvidia-uvm, and nvidia-modeset
kernel modules before generating the automatic (jit) CDI specification.
The kernel modules can be controlled by the
nvidia-container-runtime.modes.jit-cdi.load-kernel-modules
config option. If this is set to the empty list, then no kernel modules
are loaded.
Errors in loading the kernel modules are logged, but ignored.

This change adds a test for locating libcuda as a driver library.
This includes a failing test on a system where libcuda.so.1 is in
the ldcache, but not at one of the predefined library search paths.
A testdata folder with sample root filesystems is included to test
various combinations.

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.
