linux-pam: Fix build with newer glibc versions

Older versions of `linux-pam` use rpc/rpc.h which no longer
exists on current Linux systems. Update to the current PAM
release and fix its build on Ubuntu 22.04.

As PAM is a Linux-specific library, the build on Darwin is
not meaningful, fails and would fail on Windows as well.
Add conflicts for both as appropriate to fix GitLab CI.
