To support yocto on systems with python3 as default version, scripts
should use /usr/bin/env python in the shebang, as this allows the use of
a fake env to mimic python2 as default version.
This patch simply replaces occurrences of #!/usr/bin/python with
#!/usr/bin/env python and was done with this oneliner:
git grep -lE '^#!/usr/bin/python' | xargs \
sed -i 's|/usr/bin/python|/usr/bin/env python|'
