fuzz: fix an unused result on getcwd() in pyutil
clang was rightly complaining about this, so let's just fix it.
Differential Revision: https://phab.mercurial-scm.org/D7558
# dirstatenonnormalcheck.py - extension to check the consistency of the
# dirstate's non-normal map
#
# For most operations on dirstate, this extensions checks that the nonnormalset
# contains the right entries.
# It compares the nonnormal file to a nonnormalset built from the map of all
# the files in the dirstate to check that they contain the same files.
