mrblib: add parentheses to method calls with used return values

added parentheses to all `to_enum` and `super` calls where the return
value is used (returned, assigned, or passed to another method). this
makes the code style consistent with the guideline that method calls
should use parentheses when their return values are consumed.

changes:
- return to_enum :symbol -> return to_enum(:symbol)
- return to_enum :symbol, arg -> return to_enum(:symbol, arg)
- super message, name -> super(message, name)

affected files: 10error.rb, array.rb, enum.rb, hash.rb, kernel.rb,
numeric.rb, range.rb
