[OE-core] [PATCH 06/14] scripts/lib/argparse_oe: tweak title above options

[Paul Eggleton]

Naming these as "optional arguments" is perhaps slightly confusing since
some of the positional arguments might also be optional; in addition
it's rare (though possible) for options to be mandatory - up until
recently we had a recipetool option (-o) that was mandatory. It's not
perfect, but change it to "options" so it's at least a bit more
appropriate.
