Lua's package.path and package.cpath contain the string $FLATPAK_DEST instead of its value

[rolandlo]

Example:

Package path: $FLATPAK_DEST/share/lua/5.4/?.lua;$FLATPAK_DEST/share/lua/5.4/?/init.lua;$FLATPAK_DEST/lib/lua/5.4/?.lua;$FLATPAK_DEST/lib/lua/5.4/?/init.lua;./?.lua;./?/init.lua

Package cpath: $FLATPAK_DEST/lib/lua/5.4/?.so;$FLATPAK_DEST/lib/lua/5.4/loadall.so;./?.so

That doesn't work with loading the modules.

The issue comes from b0e640f and 9ad0965
