Merge pull request #2115 from Firstyear/20250327-use-flags-fping

Improve handling of -4/-6
This changes the handling of `-4`/`-6` flags for check_fping to make it more explicit which IP stack is used in which case.
Additionally, the deprecated `fping6` command is removed wholesale and the explicit `-4`/`-6` flags are used instead.
