percona: add hotfix for socat

We've added a workaround image for an issue with an old version of
socat until Percona releases new images, the following was used to
build it:

  docker buildx build \
    --platform linux/amd64 --file Dockerfile.k8s
    --tag us-docker.pkg.dev/vexxhost-infra/openstack/percona-xtradb-cluster:5.7.36-31.55-socatfix
    'https://github.com/percona/percona-docker.git#main:percona-xtradb-cluster-5.7'

We should flip this back to upstream once they release a new image.

Sem-Ver: feature
