configure: disable qemu-keymap for linux-user qemu

We don't need qemu-keymap when we build only linux-user qemu.

When we compile in static mode, the libxkbcommon is detected
by configure if the shared one is available, but cannot
be linked if the static version is not available.

As we don't need it for qemu-linux-user, and we generally need
a static link to use it in a chroot, disable qemu-keymap in
this case.
