util.ip: Fix netmask for link-local address range
This may have mistakenly caused link-local addresses to be considered
global. May have caused mod_s2s and prosodyctl check dns to behave
incorrectly on networks using link-local IPv4 addresses. By my
guesstimate, these are extremely rare. Probably minimal impact beyond
a bit longer to establish s2s and some possible confusion from
prosodyctl check dns results.
