Use more compatible hashbangs

This adds a #! line to the top of setup.py, because it is a script
with the executable bit set. Although neither recent nor current
documentation in the project recommends to run "./setup.py", this
should probably have the intuitive effect of attempting to run the
script with a Python interpreter rather than a Unix-style shell.

It also uses the "env trick" in init-tests-after-clone.sh so that
script runs with whatever bash interpreter is found in a normal
PATH search. While "sh" is expected to be found in /bin on all
Unix-like systems, that is not always the case for "bash". This
change slightly improves compatibility by supporting systems that
don't ship with bash but on which it has been installed.
