Speed up enumerate_subtree()

Searching a set is faster than searching a list, and changing this
particular spot to a set cut the function's overall execution time
by half when enumerating 200 /xyz/openbmc_project/logging objects,
from ~15s down to about 6 (with system power off).

Also removed the list() conversions that tend to be slow and aren't
really needed for python3 anyway.

Resolves openbmc/openbmc#3199
