stdlib: Move eval_str/1 from mod_esi to erl_eval

See also https://bugs.erlang.org/browse/ERL-634.

The utility program `erl_call' in erl_interface used to call
lib:eval_str/1, which is no longer present in Erlang/OTP 21.0.

The lib module was eliminated in OTP-15072, see also
https://github.com/erlang/otp/pull/1786.
