We don't need the temporary IPC$ connection used for the
SMB1 UNIX CIFS extensions encryption setup anymore,
so we can also let the server close it.

Remove the sock_exec code which is no longer needed and additionally has been
used by exploit code.
This was originally test support code, the tests relying on the sock_exec
code have been removed.
Past exploits have used sock_exec as a proxy for system() matching a talloc
destructor prototype.
See for example:
Exploit for Samba vulnerabilty (CVE-2015-0240) at

This allows source4/torture code to set the option for tests by
preparing a struct smbcli_options with max_credits set to some value and
pass that to a torture_smb2_connection_ext().
This will be used in subsequent smbtorture test for SMB2 creditting.
Behaviour of existing upper layers is unchanged, they simply pass the
wanted max credits value to smbXcli_negprot_send() instead of
retrofitting it with a call to smb2cli_conn_set_max_credits().
