Mahmoud Al-Qudsi efda4f5c39 Make zombie test smarter
Instead of trying to assert that there are no zombies when the test
starts (which often fails) and to prevent conflating existing or
irrelevant zombies with the ones we are interested in checking for,
have `ps` also emit the parent process id and filter its output to
include only children of the current fish instance.

# be gone by the time we get here. Unfortunately, kill from procps on pre-2016 distributions
# does not print an error for non-existent PIDs, so instead look for zombies in this session.
# There could already be zombies from previous tests run in this session or a test could be run
# simultaneously that causes a zombie to spawn, so limit the output only to processes started by
# this fish instance.
