Reset poky to before our libpam hacks

Things got a bit out of synch with openbmc-config due to the libpam
issues and the migration from the meta-* layers.

Revert the two previous commits and then put the latest poky in with the
libpam revert and get openbmc-config right again.

Revert "Revert "libpam: update 1.3.1 -> 1.5.1""

This reverts commit 87ddd3eab4df68e624b5350ccaab28b3b97547c0.

Revert "poky: subtree update:796be0593a..10c69538c0"

This reverts commit c723b72979bfac6362509cf1fe086900f6641f28.
