Delayed SST when running on unprivileged containers on RHEL9

When running with drop privileges on a RHEL9 host, mariadb WSREP reliance on `lsof` may cause SST to take a while before starting. The culprit is wsrep scripts preference for lsof. While ss works alright on these containers, lsof hangs forever, until the timeout defined here:

is complete.

Given logic exists to use `lsof`, `sockstat` or `ss`

CMAKE should be adjusted to list `lsof` as a soft dependency.
