ppsspp/lr-ppsspp: (bug) resolve conflict on removal

Both stand-alone `ppsspp` and the libretro core `lr-ppsspp` share the `$HOME/.config/ppsspp` save file directory.

`moveConfigDir` removes the symlink on removal; this will disconnects the existing saves from the remaining emulator.

ppsspp: Use moveConfigDir only on install.

On removal, do not use the helper function. Remove the symlink manually and only if no remaining PSP emulators.

lr-ppsspp: Libretro core did not link this dir at all, and just used mkUserDir instead. Switch to use moveConfigDir and same fix as above, for libretro core also.
