Let utilities identify themselves as being part of uutils in `--help` and `--version`

I had a tool in $PATH and needed to determine whether its from GNU coreutils/findutils/... , busybox, or uutils. While the GNU and Busybox state their origin in the --help and --version , uutils stays (mostly) silent about its origin.

Add something like part of uutils to --help and also mention uutils in the --version output.

Currently, uutils-coreutils only implements the indicator in the --version output.

Note: This bug is part of a series of bugreports across all tools of uutils. Please check wether I've covered all your utilities.

Start by inspecting the existing uutils-coreutils implementation that adds the uutils indicator to --version, then review each utility's --help and --version output. Check the related utility issues to identify coverage expectations, and verify that every coreutils utility identifies itself in both outputs without breaking existing formatting.
