An update that has nine fixes can now be installed.

## Description:

This update for kernel-livepatch-tools fixes the following issues:

Version 1.8:

  * Drop different flavors support (bsc#1245949)

  * Hardcode version 1.2 when building for older distributions than SL 16.0. The
    existing livepatch packages require exactly this version. But new versions
    are backward compatible.

  * Use "transactional-update" for downgrading livepatch package on
    transactional systems (bsc#1245346)
  * Improve the description of the LIVEPATCH_KERNEL sysconfig variable
    (bsc#1236642)
  * Use dracut to regenerate initrd when "mkinitrd" can't be found (bsc#1234757)
  * Remove week dependencies on SLE16+ to unify the behavior on SLES, SLES
    Minimal, and SL Micro (bsc#1219966)
  * cache-cleaner: Correctly handle situation when there is no livepatch loaded
    (bsc#1231422)
  * klp-info-cache.service: Expand %%{_libexecdir} when setting ExecStart. The
    cache-cleaner script has been moved in SL Micro 6.0 (bsc#1231397)
  * klp.sh: Fix downgrade with skipped package version (bsc#1223966)
  * klp.sh: Exit with an error code when downgrade fails (bsc#1223930)
