92033047a5 Python : Add query to detect PAM authorization bypass
Using only a call to `pam_authenticate` to check the validity of a login can
lead to authorization bypass vulnerabilities. A `pam_authenticate` only
verifies the credentials of a user. It does not check if a user has an
appropriate authorization to actually login. This means a user with a
expired login or a password can still access the system.

This PR includes a qhelp describing the issue, a query which detects instances where a call to
`pam_acc_mgmt` does not follow a call to `pam_authenticate` and it's
corresponding tests.

This PR has multiple detections. Some of the public one I can find are :
