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.
