package/freerdp: fix build of wayland client

Currently, FreeRDP uses pkg-config to find whether wayland is available.
When it is, it gets the CFLAGS and LDFLAGS and so on from pkg-config,
which is OK.

But I also gets the path to the wayland scanner from pkg-config. And
this points to the target one, when we really need the host one.

So we force-feed the correct path as a configure option.

Furthermore, wayland support needs libxkbcommon, so add this missing
dependency as well.
