hw-sensors.c: Reduce default delay between sensor updates.

This reduces the default delay used between sensor updates.
This is needed to fix orientation for Honeycomb emulation since
the framework's window orientation listener now discards events
if they are spaced by more than 1 second (which happened to be
the old default).
