Requiring /sys/fs/bpf path to be a mount point at the moment of cgroup controllers realization does more harm than good, because: * Realization happens early on boot, the mount point may not be ready at the time. That happens if mounts are made by a .mount unit (the issue we encountered). * BPF filesystem may be mounted on another point. Remove the check. Instead verify that path provided by BPFProgram= is within BPF fs when unit properties are parsed. Split in two commits for simple backport.
