Delete a Flymake obsolete alias that can't possibly work

The function `flymake-ler-make-ler' can't possibly work as an backward
compatible interface to existing extensinos (even purely hypothetical
ones, since none are known).  This is because every diagnostic
considered by Flymake has to passed to a report-fn function.

* lisp/progmodes/flymake.el (flymake-ler-make-ler): Delete.
