pts/memtier-benchmark-1.1.0 - 10 March 2022 - Update against upstream Memtier-benchmark 1.3 and Redis 6. Plus add pkg-config as a SystemDependencies. Below patch pointed out pkg-config is needed but it does not work as an ExternalDependencies as pkg-config is not in the XML there, but can be dynamically resolved as SystemDependencies.
