No need for configure to create etc/ and lisp/ any more

* configure.ac (etc, lisp): No need to create specially.
Configure already creates lisp when generating lisp/Makefile;
src/Makefile now creates etc when needed.

* src/Makefile.in ($(etc)/DOC, temacs$(EXEEXT)): Ensure etc/ exists.

 dnl You might wonder (I did) why epaths.h is generated by running make,
 dnl rather than just letting configure generate it from epaths.in.
 dnl One reason is that the various paths are not fully expanded (see above);
