btrfs-progs: Make option parsing more robust to code modifications

The current approach to option parsing, where long-only options are
selected on the basis of their position in the long_options array is
fragile and painful to modify if options are to be inserted into the
list, rather than appended.

Instead, use the last field of struct option to return a value which
cannot be a char (and hence a short option), and simply switch on those
within the case statement.
