Linux Build Fixes

- fixed AppImage not accepting arguments (for example -f -g ROM_file to start directly)
- adjusted AppImage build.sh so it can find Qt libs on Fedora (#98)
- perl-Digest-SHA package is needed for shasum on Fedora
- added option do disable linking against LLVM 17 (Steam Deck specific)
- updated build-for-linux.md (Steam Deck specific)
