This chagne ensures that we always treat the link path as a path
relative to the container root. Without this change, relative paths
in link paths would result links being created relative to the
current working directory where the hook is executed.

The hostRoot argument is always empty and not applicable to
how links are specified.
Links are specified by the paths in the container filesystem and as such
the only transform required to change the root is a join of the filepath.

Since hostRoot is always the empty string and we are changing the root in the
target path to /, the call to changeRoot is redundant.

This change removes support for specifying csv-filenames when
calling the create-symlinks hook. This is no longer required
as tegra-based systems generate hooks with `--link` arguments.
This also allows the hook to better serve as a reference implementation
for upstream projects wanting to implement a set of standard CDI hooks.

This change updates the create-symlinks hook to check whether
link paths resolve in the container's filesystem. In addition
the executable is updated to return an error if a link could
not be created.

This change creates an nvidia-cdi-hook binary for implementing
CDI hooks. This allows for these hooks to be separated from the
nvidia-ctk command which may, for example, require libnvidia-ml
to support other functionality.
The nvidia-ctk hook subcommand is maintained as an alias for the
time being to allow for existing CDI specifications referring to
this path to work as expected.
