[PATCH] fix the installation path for html documentation

Since 026fa0d5ad9538ca76838070861531c037d7b9ba (Move computation of
absolute paths from Makefile to runtime (in preparation for
RUNTIME_PREFIX) the installation of html doc was broken:
Documentation/Makefile does not know how to resolve relative dirs, which
results in html doc being installed in
$(git-build-root)/Documentation/share/doc/git-doc.

Fix this by not exporting htmldir from Makefile since this allows
Documentation/Makefile to compute htmldir from prefix.

An alternative would be to teach Documentation/Makefile to take the
relative htmldir and make it into an absolute path. But the approach I'm
taking with this patch as analogous to how mandir is handled, with the
same draw back. But all is well as long as the build monkey messes with
prefix only.
