sysctl: Make the header lists per directory.
Slightly enhance efficiency and clarity of the code by making the
header list per directory instead of per set.
Benchmark before:
make-dummies 0 999 -> 0.63s
rmmod dummy -> 0.12s
make-dummies 0 9999 -> 2m35s
rmmod dummy -> 18s
Benchmark after:
make-dummies 0 999 -> 0.32s
rmmod dummy -> 0.12s
make-dummies 0 9999 -> 1m17s
rmmod dummy -> 17s
