Include Makefile for CLIENT_DIST_FILES.
Include Makefile for CLIENT_DIST_FILES.

Ximin in #6810 made me realize that the client packages should include
Makefile, so "make install" works.

I may not keep making client packages because I suspect they are hardly
used and they are subsumed by the pluggable transports bundle and
upcoming Debian packages. But here this is for posterity.
