libpam: mark CVE-2025-6018 as not applicable

CVE-2025-6018 is a local privilege escalation in PAM that requires
`user_readenv=1` to be enabled in the PAM configuration. The default
configuration does not enable reading user environment files (user_readenv
is 0 by default). Hence this vulnerability cannot be exploited using the
default configuration.
