Update sudo package to 1.6.9p14.

pkgsrc changes:

- Explict to depends security/heimdal package when kerberos option is
  specified.  PR pkg/37999 should be fixed.

Change:

646) Sudo will now set the nproc resource limit to unlimited on Linux
    systems to work around Linux's setuid() resource limit semantics.
    On PAM systems the resource limits will be reset by pam_limits.so
    before the command is executed.

647) SELinux support that can be used to implement role based access
    control (RBAC).  A role and (optional) type may be specified
    in sudoers or on the command line.  These are then used in the
    security context that the command is run as.

648) Fixed a Kerberos 5 compilation problem with MIT Kerberos.

Sudo 1.6.9p13 released.

649) Fixed an invalid assumption in the PAM conversation function
    introduced in version 1.6.9p9.  The conversation function may
    be called for non-password reading purposes as well.

650) Fixed freeing an uninitialized pointer in -l mode, introduced in
    version 1.6.9p13.

651) Check /etc/sudoers after LDAP even if the user was found in LDAP.
    This allows Defaults options in /etc/sudoers to take effect.

652) Add missing checks for enforcing mode in SELinux RBAC mode.

Sudo 1.6.9p14 released.
