Revert "Move each search dns to its own line"
This reverts commit a1bc8cb52cefd49e8cc54ae14d1864b8a1ec216e.
Please see resolv.conf(5) search domains must be on the same line. If
you use multiple seach key words only the last one is used. I tested this
with alpine and it works correctly when they are on the same line so I
am not sure what issues Dan had with it but this is not correct.
