Remove not needed shebangs in sm_client

The linters in the Opensuse build service are failing because sm_client has
unneeded python shebangs in the code. This is because a python source code
file that is not intended to be executed shouldn't include this shebang.

Also, the linter fails as `/usr/bin/env python` is used causing that the
dependency discovery tool fails. It is safe to use `/usr/bin/python` as
currently we don't provide any other python version.
