core: sort addresses in captured IPv4 configuration
When IPv4 addresses are synchronized to platform, the order of IPv4
addresses matters because the first address is considered the primary
one. Thus, nm_ip4_config_capture() should put the primary address as
first, otherwise during synchronization addresses will be removed and
added back with a different primary/secondary role.
