Fix definition of LWIP_NUM_SYS_TIMEOUT_INTERNAL

Browse Source 
In timeouts.c commit 7d1c26cc0c replaced
timeout for AUTOIP with a timeout for ACD, however the value of
LWIP_NUM_SYS_TIMEOUT_INTERNAL was not updated and still counts
LWIP_AUTOIP instead of LWIP_ACD. If user has AUTOIP disabled (or not
explicitly enabled) and DHCP enabled, then ACD gets automatically
enabled too. In this case there will be one timeout too little for lwIP
and first TCP packet received causes an assertion.

Also add LWIP_IPV6_DHCP6 to the value of LWIP_NUM_SYS_TIMEOUT_INTERNAL,
as it was also not accounted for.
