all: Remove unused longindex parameter to getopt_long()
All tools (except mausezahn) use getopt_long() and pass a pointer to a local opt_index variable for the longindex parameter. However, this variable is never read afterwards. According to getopt(3) it's perfectly fine to pass NULL as the longindex parameter instead, so do that. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
