add libpam.so.0 and libpam_misc.so.0 to exclude list

Pam libraries are system specific, when using bundled PAM libs from e.g. fedora on Debian you can get an error such as Authentication failed: Module is unkown. Using system PAM libraries works completely fine, also If the system doesn't have PAM libraries I do not think PAM works at all, so there should not be any reason to bundle them.
