perf: Slightly reduce bandwidth usage when there are few nodes. 
This mainly saves spam in test logs, but may save some packets here and
there, if nodes are randomly selected twice for GET_NODES and onion
routing packets.

################################################################################
#
# The main toxcore CMake build file.
#
# This file when processed with cmake produces:
# - A number of small libraries (.a/.so/...) containing independent components
# of toxcore. E.g. the DHT has its own library, and the system/network
# abstractions are in their own library as well. These libraries are not
# installed on `make install`. The toxav, and toxencryptsave libraries are
# also not installed.
# - A number of small programs, statically linked if possible.
# - One big library containing all of the toxcore, toxav, and toxencryptsave
# code.
