This update for ntpsec fixes the following issues:

Changes in ntpsec:

- Update the unit install commands wrt boo#1153841

ntpsec was updated to 1.1.7 boo#1153841:

* The numeric literal argument of the 'time1' fudge option on a clock
can now have one or more letter suffixes that compensate for era
rollover in a GPS device. Each "g" adds the number of seconds in a
1024-week (10-bit) GPS era. Each "G" adds the number of seconds in a
8192-week (13-bit) GPS era.
* The neoclock4x driver has been removed, due to the hardware and the
vendor having utterly vanished from the face of the earth.
* The NTS ALPN negotiation sequence has been modified for improved
interoperability with other NTS implementations.
* NTS key rotation now happens every 24 hours. It used to rotate
every hour to enable testing of recovery from stale cookies.

- Actually remove ntp.firewall from sources.
- Do not install susefirewall2 service anymore

Update to 1.1.6:

* Fixes to NTS server list.
* Add ALPN for the NTS server, as required by the NTP draft.

Update to 1.1.4 should fix boo#1138728:

* NTS is now implemented
* Lots of fixes and cleanups to PPS
* Lots of minor cleanups
