An update that solves one vulnerability can now be installed.

## Description:

This update for umoci fixes the following issues:

Update to umoci v0.5.0. Upstream changelog is available from

<https://github.com/opencontainers/umoci/releases/tag/v0.5.0> bsc#1243388

A security flaw was found in the OCI image-spec, where it is possible to cause a
blob with one media-type to be interpreted as a different media-type. As umoci
is not a registry nor does it handle signatures, this vulnerability had no real
impact on umoci but for safety we implemented the now-recommended media-type
embedding and verification. CVE-2021-41190

Other changes in this release:

  * Several large reworks and API-related changes to the umoci's overlayfs
    support. This is only available to Go API users.
  * The runtime-spec config.json generated by umoci is updated to be more modern
    and work properly with modern runc versions.
  * The default gzip compression blocksize has been adjusted to match Docker.
  * zstd-compressed images are now fully supported. Users can explcitily request
    the compression algorithm for newly-generated layers with the \--compress
    option.
