This update for runc fixes the following issues:

Security vulnerablities addressed:

- CVE-2019-5736: Effectively copying /proc/self/exe during re-exec to avoid
write attacks to the host runc binary, which could lead to a container
breakout (bsc#1121967)
- CVE-2018-16873: Fix a remote command execution during "go get -u"
(boo#1118897)
- CVE-2018-16874: Fix a directory traversal in "go get" via curly braces in
import paths (boo#1118898)
- CVE-2018-16875: Fix a CPU denial of service issue (boo#1118899)

Other changes and bug fixes:

- Update go requirements to >= go1.10
- Create a symlink in /usr/bin/runc to enable rootless Podman and Buildah.
- Make use of %license macro
- Remove 'go test' from %check section, as it has only ever caused us problems
and hasn't (as far as I remember) ever caught a release-blocking issue. Smoke
testing has been far more useful. (boo#1095817)
- Upgrade to runc v1.0.0~rc6. Upstream changelog is available from
