dns: treat names rejected by res_mkquery as nonexistent rather than error
this distinction only affects search, but allows search to continue
when concatenating one of the search domains onto the requested name
produces a result that's not valid. this can happen when the
concatenation is too long, or one of the search list entries is
itself not valid.
as a consequence of this change, having "." in the search domains list
will now be ignored/skipped rather than making the lookup abort with
no results (due to producing a concatenation ending in ".."). this
behavior could be changed later if needed.
