generate-settings-docs.py script uses the `LD_LIBRARY_PATH` to prepend directories to the library search path, which is useful to load a just built libnm shared library, when generating the `nm-settings-docs.xml` and `nm-property-docs.xml` files. However, this is a problem for meson, which is not able to set environment variables when executing the script. This patch adds a new optional parameter, `-l` or `--lib-path` that can be used to pass different paths to be prepended without using the `LD_LIBRARY_PATH` environment, which can still be used.
