netlink: add getter and check existence functions

This patch adds nl_get_conntrack and it changes the behaviour of
nl_exist_conntrack. Now, nl_get_conntrack requests the kernel for
a conntrack and updates the cached entry. On the other hand,
nl_exist_conntrack only inquiries for the existence of the
entry.
