This update for libsolv, libzypp, zypper fixes the following issues:

libzypp was updated to version 17.25.1:

- Fix bsc#1176902: When kernel-rt has been installed, the
  purge-kernels service fails during boot.
- Use package name provides as group key in purge-kernel
  (bsc#1176740 bsc#1176192)
  kernel-default-base has new packaging, where the kernel uname -r
  does not reflect the full package version anymore. This patch
  adds additional logic to use the most generic/shortest edition
  each package provides with %{packagename}=<version> to group the
  kernel packages instead of the rpm versions.
  This also changes how the keep-spec for specific versions is
  applied, instead of matching the package versions, each of the
  package name provides will be matched.
- RepoInfo: Return the type of the local metadata cache as
  fallback (bsc#1176435)
- VendorAttr: Fix broken "suse,opensuse" equivalence handling.
  Enhance API and testcases. (bsc#1174918)
- Update docs regarding 'opensuse' namepace matching.
- New solver testcase format.
- Link against libzsd to close libsolvs open references
  (as we link statically)

zypper was updated to version 1.14.40.

- info: Assume descriptions starting with '<p>' are richtext
  (bsc#935885)
- Use new testcase API in libzypp.
- BuildRequires:  libzypp-devel >= 17.25.0.
- help: prevent 'whatis' from writing to stderr (bsc#1176712)
- wp: point out that command is aliased to a search command and
  searches case-insensitive (jsc#SLE-16271)
