xapp_xf86dga: fix xlib_libXaw dependency

Make it select BR2_PACKAGE_XLIB_LIBXAW, that also selects BR2_PACKAGE_XLIB_LIBXT and BR2_PACKAGE_XLIB_LIBXMU

The error message is:
Makefile:475: *** xlib_libXaw is in the dependency chain of xapp_xf86dga that has added it to its _DEPENDENCIES variable without selecting it or depending on it from Config.in. Stop.

The error can reproduced with this config BR2_TOOLCHAIN_EXTERNAL=y # easy for toolchain w/ MMU sup. BR2_PACKAGE_XORG7=y
BR2_PACKAGE_XAPP_XF86DGA=y

1.9.1

Since these two are also mentioned explicitly in the .mk, it's better to select
them as well.

However, the Changelog says:

commit 4e4c9f023d84e37de412f1f484615edca6628549

xf86dga doesn't require Xt, Xmu and Xaw.

Remove inclusion of Xt/Xmu/Xaw headers and update includes to match
missing libc and libX11 protypes.

So instead, the dependencies in the .mk file should be removed.

I'll cook a patch.
