emulators/hercules4sdl: add patch from upstream for networking crash

Fix issue https://github.com/SDL-Hercules-390/hyperion/issues/525
which can cause a segfault if networking is used.
Created a patch file from an upstream commit, therefore it patches multiple
files. It should be possible to remove it at the next release.

+Don't issue messages when setting the CODEPAGE from Hercifc, as they can wind up in the stream, corrupting data exchange with Hercules.
