emulators/Ymir: Update 0.3.0 => 0.3.1

• Upstream removed the Ymir_INCLUDE_PACKAGING build option, so the port removes it from CMAKE_OFF.

• Ymir documents all dependencies in its "About" window. This also includes the vendored miniz from the vendored libchdr dependency and requires the version constant from miniz.h. This library is currently not available as a port and the Ymir port unbundles libchdr in the first place, which is also configured to use the system-provided libz instead of miniz. Therefore remove all miniz references to unbreak the build.
