Application window class is ld-linux.so.2

[Link4Electronics]

Hello,
when making appimages that use 32-bit libs, the window class becomes ld-linux.so.2 instead of the proper name of it.

https://github.com/pkgforge-dev/ZSNES-AppImage

Can reproduce, weird:

Seems to be /proc/self/exe is wrong, as changing ARGV0 with this trick I have does not work (had to manually build the lib for 32bit to test)

NFSIISE and ZSNES they're both SDL apps, kega-fusion which is gtk2 and 32-bit didn't have this issue. maybe libdecor is related?

Alright I can see the "problem"

userland_execve is not used for pyinstaller and 32bit binaries 🤨

The likely reason behind this is that it is not possible to use userland_execve with 32bit binaries.

Well I guess this is another point for having #104 implemented.
