[ruby/fiddle] Add constants for unsigned values (https://github.com/ruby/fiddle/pull/111)
This commit adds constants for unsigned values. Currently we can use `-`
to mean "unsigned", but I think having a specific name makes Fiddle more
user friendly. This commit continues to support `-`, but introduces
negative constants with "unsigned" names
I think this will help to eliminate [this
code](https://github.com/ruby/ruby/blob/3a56bf0bcc66e14ffe5ec89efc32ecfceed180f4/lib/mjit/c_type.rb#L31-L38)
