Remove iotest macro

This commit removes the `iotest!` macro from `std::io`. The macro was
primarily used to ensure that all io-related tests were run on both
libnative and libgreen/librustuv. However, now that the librustuv stack
is being removed, the macro is no longer needed.

See the [runtime removal
RFC](rust-lang/rfcs#230) for more context.
