Hasini Gunasinghe 4fa6b1a037 Allow keystore to read and write keystore.crash_count system property.
Additionally, remove the obsolete permission which allows keystore to
register callbacks with statsd. There's no direct communication between
keystore and statsd now.

Ignore-AOSP-First: No mergepath to AOSP.
Bug: 188590587
Test: statsd TestDrive script.
