For now, link the WASM thing with the emscripten_fs_image from LO

The LO build directory in question needs to be one separately
configured for this (not one that would use Qt5 for UI, for instance),
so in the long run perhaps it does not make sense to create the FS
image there in core, but we should do it here in online? And we will
surely need additional files in the fs image anyway that core knows
nothing about.
