[xray][tests][RHDTS] Add -lstdc++ after LLVM libs, resolving link error with RHDTS

Summary:
A link error was encountered when using the Red Hat Developer Toolset.
In the RHDTS, `libstdc++.so` is a linker script that may resolve symbols
to a static library. This patch places `-lstdc++` later in the ordering.
