use sed instead of perl, add target clean-install

	* Makefile, lisp/Makefile, doc/Makefile: add target clean-install
	to remove files in install-directories

	* default.mk: add customization variable $(SED)

	* doc/Makefile: do not remove dir while cleaning

	* lisp/Makefile: use sed instead of perl to weave git-status into
	org.el and ignore any errors while doing it.  Keep git status in
	$(GITSTATUS) to make it more clear what happens in the check.
