[lldp]: LLDP is misbehaving if netlink messages were lost due to timing issue. (#1909)

Browse Source 
The behavior could be that we are sending LLDP message but not using
lldpcli configured properties if netlink delete messages were lost.

It also could be that some interfaces do not sending messages at all.
"lldpcli show statistics" could see duplicated or missing interfaces.

Changes:
Upgrade lldpd to 0.9.6 (which introduced the adjustable netlink buffer size)
Change the netlink receive buffer size to 1MB
