Clear secure deletion keys upon factory reset

This ports the gs101 configuration - which clears the secure
deletion keys upon factory reset - to (REDACTED DEVICE), as
suggested by David Drysdale in b/223934835#comment53. In the
absence of this change, the key slots may eventually get filled
up (e.g., by failing tests) and never be released.

Bug: 223934835
Test: Check logcat that keys are cleared after factory reset
