Increase time b/w UDFPS fails on AOD for bouncer

Browse Source 
When UDFPS is attempted (and failed) within x seconds,
we bring up the bouncer after 2 consecutive failures.

Since UDFPS authentication takes longer on AOD:
- on AOD, consecutive attempts is considered failures within 3.5 seconds
* on LS, consecutive attempts is considered failures within 2 seconds

Test: manual
