"get_local_port_mac" in ovs_lib uses an only Linux command, brokes Windows compatibility

[Rodolfo Alonso]

neutron/agent/common/ovs_lib:OVSBridge is mented to be compatible both for Linux and Windows.

In function "get_local_port_mac", the IP Linux lib is called, instead of the ip_lib wrapper in neutron/agent/common.

The solution to this problem is:
- To call the ip_lib in neutron/agent/common.
- To write the function to read the MAC address in the IPDevice class implementation for Windows.
