Subject: [PATCH] Docs build: depend on locally built nix executable and not
 installed one

Previously many of the documentation targets were depending on
$(bindir)/nix which is the installed version. This meant that its
install rules would be triggered (which in chain would also trigger
the install of libraries, as reported in #5140). Therefore a build
of the documentation without an installation would not be possible
(which apart from doing unwanted operations it may also generate
permission problems for example).
The fix makes the rules depend on $(nix_DIR)/nix instead, which is
the executable in the build tree.
