timers/migration: Rename childmask by groupmask to make naming more obvious
childmask in the group reflects the mask that is required to 'reference'
this group in the parent. When reading childmask, this might be confusing,
as this suggests, that this is the mask of the child of the group.
Clarify this by renaming childmask in the tmigr_group and tmc_group by
groupmask.
