dhcp: drop NMDhcpClientClass.get_duid() hook

Note that there are no callers of nm_dhcp_client_get_effective_client_id(),
hence calling the setter had no effect. This is a bug, that we will fix
later.

But before fixing the bug, change how this works. Drop the get_duid() hook.
It's only confusing and backward.

We will keep the nm_dhcp_client_[gs]et_effective_client_id() functions.
They will be used later.
