[Buildroot] [PATCH] vala: fix documentation build problem

On gcc10, the build of the host-vala documentation causes a
segmentation fault of xsltproc, for some unknown reason. See:

  http://autobuild.buildroot.org/results/42fea25ac4fe33a56c02d90c361da1c494f79ba3/build-end.log

Therefore, this patch fixes the problem by:

 * Ensuring that host-libxslt is amongst the dependency of vala (vala
   for the target) so that we build a well-known version of
   libxslt/xsltproc.

 * Disabling the build of the documentation for host-vala. Note that
   we need to pass ':' as the xsltproc binary name to teach the
   configure script that xsltproc is not available.
