ntp: Update to version 4.2.8p17

- Update from version 4.2.8p15 to 4.2.8p17
- Update of rootfile not required
- Tested out on vm testbed. Time correctly updated every hour and pakfire was able to
   download and install various addons without any problems indicating that the time
   is working correctly.
- patch to enable build with glibc-2.34 no longer needed. ntp updated to work correctly
   with glibc-2.34 but IPFire running with version 2.37. Version 2.4.8p17 built without
   any problems without the patch.
