lldp: add proper ref counting to sd_lldp object and a separate call for setting the ifindex

Let's make sd-lldp a bit more like sd-ndisc ant the other APIs, and add proper
ref counting and a separate call for setting the ifindex.

This also adds a new lldp_reset() call we can use at various places to close
all fds. This is also similar to how sd-ndisc already does it.
