core: rename cgroup_inotify_wd → cgroup_control_inotify_wd

Let's rename the .cgroup_inotify_wd field of the Unit object to
.cgroup_control_inotify_wd. Let's similarly rename the hashmap
.cgroup_inotify_wd_unit of the Manager object to
.cgroup_control_inotify_wd_unit.

Why? As preparation for a later commit that allows us to watch the
"memory.events" cgroup attribute file in addition to the "cgroup.events"
file we already watch with the fields above. In that later commit we'll
add new fields "cgroup_memory_inotify_wd" to Unit and
"cgroup_memory_inotify_wd_unit" to Manager, that are used to watch these
other events file.

No change in behaviour. Just some renaming.
