This is mandated by the Fedora packaging guidelines because it is a security
vulnerability otherwise in suid scripts. While Xen doesn't have suid scripts,
it's a very good idea generally because it prevents the users local python
environment interfering from system packaged scripts.
pygrub is the odd-script-out, being installed by distutils rather than
manually with INSTALL_PYTHON_PROG. distutils has no nice way of editing the
shebang, so arrange to use INSTALL_PYTHON_PROG for pygrub too.
