This change aligns the creation of symlinks under CDI with
the implementation in libnvidia-container. If the driver libraries
are present, the following symlinks are created:
* {{ .LibRoot }}/libcuda.so -> libcuda.so.1
* {{ .LibRoot }}/libnvidia-opticalflow.so -> libnvidia-opticalflow.so.1
* {{ .LibRoot }}/libGLX_indirect.so.0 -> libGLX_nvidia.so.{{ .Version }}

This change refactors the use of the symlink filter to make it extendible.
A blocked filter can be set on the Tegra CSV discoverer to ensure that the correct
symlink libraries are filtered out. Here, globs can be used to select mulitple libraries,
and a **/ prefix on the globs indicates that the pattern that follows is only applied to
the filename of the symlink entry in the CSV file.
A --csv.ignore-pattern command line argument is added to the nvidia-ctk cdi generate
command that allows this to be set.

This change improves the testibility of the CSV discoverer.
This is done by adding injection points for mocks for library discovery and
symlink resolution.
Note that this highlights a bug in the current implementation where the
library filter causes valid symlinks to be skipped.

In order to properly handle systems with both iGPU and dGPU
drivers included, we skip "sym" mount specifications which
refer to .so or .so.[1-9] files.
