--exclude-library option being ignored

[JulianGro]

When I try to package something with --exclude-library=libnss3.so, ``libnss3.so` still gets included in the AppDir and AppImage.

E.g.:

~/temp/linuxdeploy-x86_64.AppImage --appdir build/AppDir --executable build/interface/interface --exclude-library=libnss3.so --output appimage --plugin qt --icon-file interface/icon/interface.svg --desktop-file interface/org.overte.interface.desktop
