libutils -= libprocessgroup dep

:)

This pulls in quite a few things into a lot of processes. Removing it
separately, in case the use of SetTaskProfiles needs to be reverted,
removing this as well might cause that revert to have linker errors
if new static users of libutils are introduced in the meantime.
