Add missing GUI dependencies to AppImage

[git-developer]

The GUI fails to start when the latest AppImage (v0.5.4) is run, at least on batocera (v42):

$ ./sc-controller-0.5.4-jammy-x86_64.AppImage gui
** (process:8247): WARNING **: 16:00:27.579: Failed to load shared library 'libgdk-3.so.0' referenced by the typelib: libwayland-cursor.so.0: cannot open shared object file: No such file or directory
Traceback (most recent call last):
  File "/tmp/.mount_sc-con6cTGDx/usr/bin/sc-controller", line 8, in <module>
    sys.exit(main())
[...]
AssertionError

This seems to happen due to a missing dependency:

$ ./sc-controller-0.5.4-jammy-x86_64.AppImage --appimage-extract
$ ldd squashfs-root/usr/lib/x86_64-linux-gnu/libgdk-3.so.0
[...]
	libwayland-cursor.so.0 => not found
	libwayland-egl.so.1 => not found
	libwayland-client.so.0 => not found

Fix was tested against a custom AppImage build

May I ask if there's a schedule for the next release?
