Workaround for conflicting with module nf_conntrack_netlink

This module uses conntrack events to register a callback function. In the same netns, only one callback method can be registered, that causes conflicts with nf_conntrack_netlink, which also uses conntrack events. Qualcomm Shortcut FE has introduced a patch to allow multiple callbacks to be registered. To apply, put this patch into target/linux/generic/hack-4.14.
