bpo-37760: Constant-fold some old options in makeunicodedata. (pythonGH-15129)

The `expand` option was introduced in 2000 in commit fad27ae.
It appears to have been always set since it was committed, and
what it does is tell the code to do something essential.  So,
just always do that, and cut the option.

Also cut the `linebreakprops` option, which isn't consulted anymore.
