full diff: seccomp/libseccomp-golang@32f571b...689e3c1

Release notes:

* Version 0.9.1 - May 21, 2019
- Minimum supported version of libseccomp bumped to v2.2.0 (seccomp/libseccomp-golang@fc02980)
  - PowerPC and S390(x) architectures are unavailable below library version v2.3.0 and will return errors if used with incompatible libraries
- Use Libseccomp's `seccomp_version` API to retrieve library version
- Unconditionally set TSync attribute for filters, due to Go's heavily threaded nature
- Fix [CVE-2017-18367](https://nvd.nist.gov/vuln/detail/CVE-2017-18367) - Multiple syscall arguments were incorrectly combined with logical-OR, instead of logical-AND (seccomp/libseccomp-golang@06e7a29)
- Fix a failure to build on Debian-based distributions due to CGo code
- Fix unit test failures on 32-bit architectures
- Improve several errors to be more verbose about their causes
- Add support for SCMP_ACT_LOG (with libseccomp versions 2.4.x and higher), permitting syscalls but logging their execution
- Add support for SCMP_FLTATR_CTL_LOG (with libseccomp versions 2.4.x and higher), logging not-allowed actions when they are denied
