Using '?' as option did not work, and would be strange to pass anyway,
because it's a glob char for the shell and you would have to escape it
like ./ubihealthd -\? … use the more common -h/--help instead.
Note: this does not touch the output, just changes the options itself.

`getopt_long()` requires a null terminated array, otherwise we get
segfaults when passing invalid options.

ubihealthd is a simple daemon which scans every PEB
of an UBI device in random order.
It helps to deal with read disturb on systems which either
reboot seldom, use fastmap or read few data.
To use this daemon you need Linux >= v5.1.
