[PATCH v2 5/7] tools: Use -s for python shebangs

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

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 on pygrub too.

v2:
 * Remove accidental setuputils dependency.
