[PATCH] libpam: fix multilib packaging issue for pam-plugins

[Ming Liu <ming.liu@windriver.com>]

libpam might miss ABI specific dependencies for pam-plugins-*, for RPM uses
generic names to check the packages depending on it and doesn't consider the
arch, which will lead to packaging issues in multilib build.

pam_plugin_hook is added because the plugin packages are dynamically
generated, so we need to manually process multilib names by add baselib to
RPROVIDES/RDEPENDS as ABI specific tag.
