Run the samba testparm(1) utility against /etc/samba/smb.conf.
We do not use apport's command_output() method here because:
- we need to discard stdout, as that includes smb.conf
- we want to know if its exit status is not zero, but that in itself
is not an error in the test itself. command_output() would say the
command failed and that would be confusing.
Returns stderr and the exit code (as a string) of testparm as a tuple or
None in the case of an error.
