Subject: Improve xkb config root detection

Relevant part from libxkbcommon's configure.ac file:

xkb_base=`$PKG_CONFIG --variable=xkb_base xkeyboard-config`
if test "x$xkb_base" = x; then
xkb_base=$datadir/X11/xkb
fi
AC_ARG_WITH([xkb_config_root],
[AS_HELP_STRING([--with-xkb-config-root=<path>],
[Set default XKB config root (default: xkeyboard-config install path)])],
[XKBCONFIGROOT="$withval"],
[XKBCONFIGROOT="$xkb_base"])
AC_SUBST([XKBCONFIGROOT])

This patch implements an equivalent logic in Qt's configure script (with some
additions).
