Subject: [PATCH] Expand the spec for erl_epmd:listen_port_please/2

The spec for erl_epmd:listen_port_please/2 is overly strict, resulting in
dialyzer errors for the valid snippet:

[Name, Host] = string:split(atom_to_list(node()), "@"),
R = erl_epmd:port_please(Name, Host),

This commit relaxes the spec for listen_port_please to match that of
port_please
