Fix CBMC proofs for DNS (#718)

Browse Source 
* Use CBMC XML output to enable VSCode debugger (#673)

Prior to this commit, CBMC would emit logging information in plain text
format, which does not contain information required for the CBMC VSCode
debugger. This commit makes CBMC use XML instead of plain text.
