[IPHLPAPI_APITEST] Avoid crash on ROS and failure on Windows. CORE-14411

Browse source 
- Make the reply buffer for IcmpSendEcho large enough to hold the reply,
  even when testing a smaller size. This avoids a buffer overflow with ROS's
  broken implementation.
- Avoid unnecessary initialization.
- Fix IcmpSendEcho return value check to succeed on Win2003.
- Don't free a string literal in the GetInterfaceName test.
