libc/inet/resolv.c: use dn_{comp,expand} for {en,de}code_dotted

Minimal-invasive change: just ifdeffing away the older code.

There is no reason to have two different sets of functions doing
the same thing, one used in half the code and another, doing less
escaping, in the other half; just use one.
