Increase power-press timeout

Preivously, Keyguard would try to authenticate after a cancellation
too quickly so the HAL would drop the attempt.

Repro steps:
 1. User press power key
 2. Keyguard cancel 1st authentication and send cancellation reqeust to HAL
 3. HAL is dealing with cancelation request
 4. Keyguard runs 2nd authentication.
 5. HAL report cancellation to keyguard and cancel 2nd authentication.
 6. Fingerprint does not respond to user's touch.
