Fabien Boucher 31b83dd2e8 Remove ununecessary shebangs
The commands are managed as entry-points so remove
ununecessary shebangs. Also lib/re2util.py does not
require a shebang as well.

zuul_return.py does not have a main and is not supposed
to be run directly.

Ununecessary shebangs for non executable script causes
rpmlint issues.
