db_get_auth_data / db_get_auc: clarify return values

Differentiate between "IMSI unknown" and "IMSI has no auth data": in case of
known IMSI lacking auth data, return -ENOKEY instead of -ENOENT.

Fix API doc comments to reflect what the functions actually return, on top of
adding the -ENOKEY detail.

Adjust db_test expectations from -ENOENT to -ENOKEY where appropriate.

Adjust VTY and CTRL command rc evaluation.

A subsequent patch will use these return values to log details on each of these
situations.
