Cherry pick of #8085 on release-v3.27.

#8085: Allow custom cgroup2 path

Original PR Body below

Description

Currently, the mount-bpffs init container tries to create the folder /run/calico/cgroup for mounting the cgroupv2 fs

This causes issues on distros like Talos Linux as described in the issue #7892

This can be a configurable path instead
