PxeBcDhcp6GoogleTest's MultipleDnsEntries test started to fail
with stack cookies added for host applications. Debugging this
showed that the test was attempting to copy two UINT16s to a
UINT8 Data[1] array allocated on the stack. This was moved to
a heap based allocation for a UINT32 to accommodate the proper
size. After this fix, the unit test passed with stack cookies
enabled.
