erlang: Use Automake SUBDIRS instead of a manual forwarding rule

Previously, lib/erl/Makefile.am would forward rules like "all" and
"clean" to the src subdir by manually invoking a submake.  However,
specifying src as a SUBDIR accomplishes this more easily and also
ensures that other rules like "distclean" work.
