Command line arguements are not preserved by the updater, and this causes an issue when the updater restarts Ryujinx in portable mode as it will create/use/modify its default directory instead.
This simple pull addresses the first part of #1594
As far as the second part of the issue, where the updater perhaps overzealously deletes everything but log files and folders, which causes problems in portable installs with a user subfolder or something else inside the Ryujinx folder.
Perhaps an UpdateList.txt containing a list of files that the updater deletes is included in the ryujinx.zip/tar.gz/etc and placed in the upacked directory for the updater to use upon the next upgrade.
The build system can run something like `forfiles /s /m *.txt /c "cmd /c echo @relpath"` or the correct command for the OS and include it in the distribution, or it could be generated by the updater itself.
