Mitigate LSKF leaks through the LockscreenCredential in KeyguardManager

This CL adds try-with-resources around LockscreenCredential objects,
in order to call `close()` when the resource is done being used.
This also clears the LSKF `byte[]` representation in the LockscreenCredential.

This CL applies the above changes to the KeyguardManager.
