Do not populate RTAX_NETMASK when sending a routing message for RTF_HOST
entries.
This is a noop with the radix routing table because rt_mask() is always
NULL for RTF_HOST entries, but it preserves the old behavior with ART.
With the ART routing table host entry always have a prefix length equals
to the length of the address.
Fix a regression reported by semarie@.
ok semarie@, bluhm@
