KH2: Fix nondeterministic generation when CasualBounties is enabled (#5967)

When CasualBounties was enabled, the location names in
`exclusion_table["HitlistCasual"]` would be iterated into
`self.random_super_boss_list` in `generate_early`, but
`exclusion_table["HitlistCasual"]` was a `set`, so its iteration order
would vary on each generation, even with same seed.

Random location names would be picked from `self.random_super_boss_list`
to place Bounty items at, so different locations could be picked on each
generation with the same seed.

`exclusion_table["Hitlist"]` is similar and was already a `list`,
avoiding the issue of nondeterministic iteration order, so
`exclusion_table["HitlistCasual"]` has been changed to a `list` to
match.
