Reabse to latest release of pam_ssh_agent_auth with preserving current functionality

Browse Source 
* Rebase to latest upstream version
 * Clean up older patches for pam_ssh_agent_auth
 * Remove prefixes from upstream release so we can build it against current
   openssh library
 * Remove copied files and headers so we make sure we build against current openssh
