Update sudo pacakge to 1.7.7.  It is maintenance release.

What's new in Sudo 1.7.7

 * I/O logging is now supported for commands run in background mode
   (using sudo's -b flag).

 * Group ownership of the sudoers file is now only enforced when
   the file mode on sudoers allows group readability or writability.

 * Visudo now checks the contents of an alias and warns about cycles
   when the alias is expanded.

 * If the user specifes a group via sudo's -g option that matches
   the target user's group in the password database, it is now
   allowed even if no groups are present in the Runas_Spec.

 * "sudo -i command" now works correctly with the bash version
   2.0 and higher.  Previously, the .bash_profile would not be
   sourced prior to running the command unless bash was built with
   NON_INTERACTIVE_LOGIN_SHELLS defined.

 * Multi-factor authentication is now supported on AIX.

 * Added support for non-RFC 4517 compliant LDAP servers that require
   that seconds be present in a timestamp, such as Tivoli Directory Server.

 * If the group vector is to be preserved, the PATH search for the
   command is now done with the user's original group vector.

 * For LDAP-based sudoers, the "runas_default" sudoOption now works
   properly in a sudoRole that contains a sudoCommand.

 * Spaces in command line arguments for "sudo -s" and "sudo -i" are
    now escaped with a backslash when checking the sudoers file.
