Fix handling of large DHCP expiry values.

They would overflow a signed 32-bit time_t on 32 bit architectures. This
was taken care of, but a compiler optimisation makes this behave
erratically. This could be resolved by adding a -fwrapv flag, but
instead we can check the value before adding the current timestamp to
it.

In the lease file values are still wrong though:

  option dhcp-rebinding-time -644245096;
