[bluetooth] Shorten suspend blocking on bluez activity. Fixes JB#34498

Blocking suspend on bluetooth activity is done to make it more likely
that upper levels of the sw stack have time to process bluetooth related
changes in display off scenarios. However blocking suspend for full five
seconds is too much and can cause unwanted battery drain in situations
where bt scanning is active for long periods of time.

Shorten the suspend blocking time from five seconds to two.
