games-util/ucon64: add 2.2.1

- add IUSE debug, usb, zlib
- set default discmage.so path not to need user intervention
- shorter elog given ucon64's output already mentions .ucon64/dat
- use fixes suggested by upstream in bug #753950

Closes: https://bugs.gentoo.org/753950
Signed-off-by: Ionen Wolkens <ionen@gentoo.org>
