XKB issue in qt5 appimage

[g1itch]

Some strange XKB issue is appeared recently with the appimage built from qt5-wip:

2021-07-06 18:28:21,041 - WARNING - Using default logger configuration
xkbcommon: ERROR: failed to add default include path ././/share/X11/xkb
Qt: Failed to create XKB context!
Use QT_XKB_CONFIG_ROOT environmental variable to provide an additional search path, add ':' as separator to provide several search paths and/or make sure that XKB configuration data directory contains recent enough contents, to update please see http://cgit.freedesktop.org/xkeyboard-config/ .

Keyboard input is not functional!

It's probably related to binpatch: true parameter in the appimage recipe. If run with QT_XKB_CONFIG_ROOT=/usr/share/X11/xkb, keyboard is working again.
