core/platform: fix wrong calculation of address lifetime/preferred for kernel addresses

Browse Source 
When receiving an IPv4/IPv6 address from the kernel, platform set the
timestamp to an invalid value before. The address timestamp must be set
to *now*, because the lifetime and preferred arguments are counting from
now.
