[Buildroot] [PATCH v1] qt5base: fix keyboard input in case of libinput usage

[Peter Seiderer]

The libinput keyboard support needs libxbcommon to gain
a functional keyboard input. Avoids the following runtime
warning:

  qt.qpa.input: X-less xkbcommon not available, not performing key mapping

I already tried to enable xkbcommon manually to fix that issue... but 
then I get:

# cd /usr/lib/qt/examples/touch/fingerpaint/
# ./fingerpaint
xkbcommon: ERROR: failed to add default include path /usr/share/X11/xkb
Failed to create xkb context

I guess that the files in that directory are normally provided by X11.

My workaroud is to disable libinput using QT_QPA_EGLFS_NO_LIBINPUT for 
keypad input.

Wolfgang.
