Replace nullable from primary keys in tz_network_bindings with default

Columns vlan_id and phy_uuid were both nullable and primary keys.
Primary keys cannot be nulls. This situation caused problems in
autogenerating scripts creating always migration that set these columns
to nullable.

Instead of having primary keys nullable this patch creates a default
values.
