tests: test-with-fake-dists: clean up *just* the pycryptopp-0.5.24 eggs when exiting

also don't set the PATH and PYTHONPATH, which is unnecessary for this test
also wrap the behavior in a couple of functions, just for tidiness

# We put a fake "pycryptopp-0.5.24.egg" package and a fake
# "pycryptopp-9.9.99.tar.gz" into a directory, but the latter is
# booby-trapped so it will raise an exception when you try to build
# it.
# Then we run "python setup.py test -s
# buildtest.test_with_fake_dist", which imports pycryptopp
# and passes if pycryptopp.__version__ == '0.5.24'.
# (If building succeeded -- meaning that you didn't try to build the
# booby-trapped 9.9.99 -- but pycryptopp.__version__ != '0.5.24' then
# that means a different version of pycryptopp was already installed
# so neither of the two fake pycryptopp packages were needed. In that
# case this test should be treated as a "skip" -- the functionality
# under test can't be exercised on the current system.)
# The goal is to turn red if the build system tries to build the
# source dist when it could have used the binary dist.
# (Note that for this test to make sense, tahoe-lafs needs to be
# asking for a version of pycryptopp which can be satisfied by either
# 0.5.24 or 0.5.25. At the time of this writing it requires >= 0.5.20
# on x86 and >= 0.5.14 on other architectures.)
