Migrate examples into a subcrate

Fuchsia doesn't support yet mio, and there is unfortunately no
way to run the rustls on Fuchsia as the crate is currently setup.
Unfortunately there is no way to make dev-dependencies optional (see
https://github.com/rust-lang/cargo/issues/1596), so this patch
migrates the examples into a subcrate so we can compile the
rustls tests without mio.
