TIAN Yuanhao 489e38fd2c package/ntp: add upstream-provided patch to fix regression
This patch fixes a regression [1] introduced in ntpd 4.2.8p18 [2].

  ntpd[200]: Listen normally on 3 lo [::1]:123
  ntpd[200]: bind(20) AF_INET6 [fe80::bf3d:254d:dee0:d345%3]:123 flags 0x811 failed: Cannot assign requested address
  ntpd[200]: unable to create socket on enp0s3 (4) for [fe80::bf3d:254d:dee0:d345%3]:123
  ntpd[192]: daemon control: got EOF
  ntpd[192]: daemon child died with signal 11
  systemd[1]: ntpd.service: Control process exited, code=exited, status=70/SOFTWARE
  systemd[1]: ntpd.service: Failed with result 'exit-code'.
  systemd[1]: Failed to start Network Time Service.

If the IPv6 link-local interface was not ready for binding on the first
attempt, ntpd would segfault in update_interfaces(). The segfault would
only occur when ntpd was started as part of the boot sequence. Most
- but not all - boots were affected. Evidently it could happen that the
timing of ntpd's start up was delayed enough that the IPv6 link-local
interface was ready for the bind() call when it was first issued by
open_socket() via create_interface().
