host: cope with large DNS responses.
DNS responses were limited to 512 bytes back when they were UDP only, but if you have a TCP connection you can get up to 64KiB. Also use the existing constant for the size of rrname. Also update the help text. Also consistently use `sizeof(T)` rather than `sizeof T`. Also use consistently use `ARRAY_LEN`. Fixes #56. Test: `toybox host value.testing.express`
