Subject: Fix initialization of erl_call

Previously erl_call relied on the implicit initialization made
of the ei-lib if no explicit initialization had been done. This
implicit initialization was utterly broken and was removed in
erl_interface-3.11 (OTP 21.3) since it has been documented for
a very long time that an explicit initialization is required.
