cpuset: replace 'kind' with an 'effective' boolean

Browse Source 
All of our users of this function currently either pass
'effective_cpus' or nothing (undef), and in cgroupv2 the
effective-cpuset file uses a different naming scheme.

Since this is only a distinction between "intended" and
"effective", use this as a boolean instead, for easier
future cgroupv2 support.
