Some sysinv source code files include a WR standard license

[Ghada Khalil]

Brief Description
-----------------
The following sysinv files include a standard WR license:
sysinv/db/sqlalchemy/migrate_repo/versions/078_interface_class.py
sysinv/db/sqlalchemy/migrate_repo/versions/079_network_column_remove.py
sysinv/db/sqlalchemy/migrate_repo/versions/088_networktype_remove.py

These need to be corrected to the Apache-2 license.

Severity
--------
Minor, but should be corrected.

Steps to Reproduce
------------------
- Go to the starlingx sysinv github
https://review.opendev.org/gitweb?p=starlingx/config.git;a=tree;f=sysinv/sysinv/sysinv/sysinv/db/sqlalchemy/migrate_repo/versions;hb=HEAD
- Verify the license for the above files

Expected Behavior
------------------
The license should be as follows:
#
# Copyright (c) 2013-2016 Wind River Systems, Inc.
#
# SPDX-License-Identifier: Apache-2.0
#

Actual Behavior
----------------
Instead the license is:
#
# Copyright (c) 2018 Wind River Systems, Inc.
#
# The right to copy, distribute, modify, or otherwise make use
# of this software may be licensed only pursuant to the terms
# of an applicable Wind River license agreement.
