Kyle Evans f3c488fc6b libutil: avoid an out-of-bounds read in trimdomain(3) 
memchr(3) will happily believe we've passed in a valid object, but
hostsize could easily exceed the bounds of fullhost.  Clamp it down to
the string size to be safe and avoid UB.  This plugs a potential
overread noted in the compat shim that was just added.
