example: Use no_std, and delay using embedded-hal

Browse source 
This does not make any difference in the concrete example
(linux-embedded-hal's delay is implemented in terms of std::thread), but
it removes a stone from the path of people who start from the example
towards an actual use of embedded hal. (They'll still have to find
suitable replacements for env_hal and linux_embedded_hal, but that's
the parts that have to be.)
