dccee4e87b Fix regression from commit 137e80cd86
Problem:

A false-negative in check-config.sh for cgroups v2 systems was fixed but the
commit introduced a regression based on a small assumption that content of
/sys/fs/cgroup/cgroup.controllers would have the same format as the content
of /proc/self/cgroup. It doesn't.

Solution:

This just tweaks the regex to count occurrences of either cgroup
subsystem-names on each line (as occurs in the sysfs pseudo-file), or those
names with colons either side (as occurs in the procfs pseudo-file).

137e80cd86 Handle cgroup v1/2/hybrid in check-config.sh more explicitly/accurately
Problem:
 In check-config.sh assumptions are made about cgroups v1/v2/hybrid,
 causes false-negative on pure V2 system.

Solution:
 In check-config.sh implement the same validation as found in
 ./pkg/agent/run.go -> validate(), validateCgroupsV1(), validateCgroupsV2()
 [ which use containerd/cgroups:utils.go -> Mode() ]

eabc82c724 Remove trailing whitespaces
To please my OCD, and remove my editor flashing boxes,
I am removing trailing whitespaces. They have no purpose in life.

5b98d10e4b Warn if NPC can't start rather than fatal error
If the ip_set kernel module is not available we should warn
that the network policy controller can not start rather than
cause a fatal error.

Also adds module probing and config checks for ip_set.
