Do dummy GPIO reads on startup

Do a read of all of the button GPIOs after they are configured
but before the sd_event handling has been set up to prevent
a spurious sd_event callback as soon as the event loop starts.

Without these, a button released signal gets sent every time
the application starts.

Tested: Saw that the spurious callbacks went away.
