[HIGH]python-clang_5.0.post2.bb - move in the separate layer (building proprietary graphics)

[iusyk]

BTW, we already have a separate layer for building proprietary graphics packages. I believe that python-clang_5.0.post2.bb recipe should live there. In this case, we don't need this fix at all. steps move recipe python-clang_5.0.post2.bb reveet commit based at https://github.com/xen-troops/meta-xt-prod-devel/pull/347

May be I'm wrong, but I suspect that issue is fixed after merge of https://github.com/xen-troops/meta-xt-images/pull/211 and may be closed.
