Build warning cleanup policyengine.cpp unit test

This cleans up [-Wcomment] warning from gcc.

This warning is given if comments end in the '\',
i.e. the line continuation character, because this
will cause the comment to be wrapped to the next
line of code.

This removes the error without changing the code.
