Unify python executables to use `#!/usr/bin/env python` shebang (#2102) * fixed shebangs in tools (and lib) * fixed shebangs in examples * do not mangle shebangs in rpm spec * renamed style-check.sh to c-style-check.sh * factored out python linter to a separate file * added shebang validation to the py-style-check * added shebangs to all python executables
