meta-ampere: pam: set default unlock time to 1800

Ampere account lockout policy is defined as:
'Five consecutive failed login attempts will lock the account for 30 minutes".
While the login attempt was set to 5 already, the 30-minute lock period
(auto-unlock) has not been set.
This commit adds the missing 30-minute lockout by default.

Tested:
1. Enter WebUI -> User management
2. Click on Account policy settings and check if:
  - Max failed login attempts: 5
  - User unlock method: Automatic after timeout
  - Timeout duration (seconds): 1800
