Fix auto updater when RPCS3_CONFIG_DIR is set

[vieiraa]

Replace GetEmuDir() with GetExeDir() in handle_rpcs3. If RPCS3_CONFIG_DIR is set, the update will be extracted there, and not in the exe folder.
Not sure on how to test this, though.

[Nekotekina]

Well, what's the problem to test?

[RipleyTom]

Makes sense, presumably the dev_hdd0 stuff should go in the in GetHddDir() dir rather than config/exe dir but it's not critical(as it only contains samples).

[Nekotekina]

Sorry that I had to revert it, maybe rpcs3 is just not ready for changing config location on windows.

[vieiraa]

Sorry for the trouble. I will think of a better solution

[MSuih]

It might have something to do with wimdows using \ as file separator, maybe the issue is with GetExeDir. But thats just a guess

[vieiraa]

Is there a way to test the updater? Can I do a "fake" update to test it?

[Megamouse]

You just need to manually search for updates on local builds and it tries to update to master.
The option is somewhere in the menu bar in the main window.

[RipleyTom]

Yeah the problem is indeed GetEmuDir returns a unix style path with /s and GetExeDir returns a windows style path with \s and the rest of the windows path assume it's unix path. The change is still a good idea though, just need to change the '/' to '\' in code.

Sorry I couldn't test and yes you can test just for an update with "Check for update" under Help.
