The replacement is to use cgroups v2, where all controllers are
always joined, so this setting is not useful.

JoinContollers= was removed in 143fadf369a18449464956206226761e49be1928
because of a) cgroupsv2, b) it was broken, c) it appears almost
nobody was using it (which is also confirmed by the fact that nobody
reported that it doesn't work as documented...).

Sorry if that's disappointing, but you'll need to switch and/or adjust.
