core: str::as_slice is unneeded, yay! fixes std::net::tcp socket_buf test

i mistook an "unconstrained type" error, due to type-inference messup
because i didnt have return vals in some closure wired-up right, for being
due to not having a str as a str/& (a str will actually auto-coerce to a
str/&, so str::as_slice was erroneously added. my bad).
