Use proper python version

since we work with python2 only, mentioning it in all shebangs make
the commands from git work even when python3 is set as default.

This also fixes one test where command being ran is 'virt-xml' through
subprocess.Popen().

While at that, add '-tt' where possible in order to make everyone use
same indentation characters.
