Subject: [PATCH] Turn on platform.callback-nontrivial

This example uses `Event` with `Callback` which means
`platform.callback-nontrivial` needs to be `true`. Turn this on in the
app, as we're planning to make `false` the default in Mbed OS.

This option is new on master, so this change would stop the example
compiling on 5.15 or earlier.
