[edk2-test] [PATCH] Fix missing symbols on edk2-test build

[Grant Likely <grant.likely@arm.com>]

EDK2 has removed some deprecated function wrappers. The BlackBoxTest
still uses StrnCpy() and UnicodeValueToString(). This patch fixes the
build by moving to UnicodeValueToStringS(). However, the code using
StrnCpy() is simply #ifdef'd out because on reading the code it is
apparent that the testcase is non-functional and the fix is not
straightforward. As I understand it, there are no functional
implementations of the interface in the wild anyway. If/when it does
become important someone can do the work of making a proper test case.

Fixes: Bug 2068
