Port pam-any from pam-bindings to nonstick crateHEADmain

The pam-bindings crate has a critical bug where pam_try! returns
PAM_SUCCESS on error in release builds (anowell/pam-rs#16), causing
authentication to always succeed. This replaces it with nonstick
and a custom pam_client module with raw PAM FFI for thread-safe
conversation forwarding.
