This fixes linking errors when test cases based on Unity fixture are defined in a .cpp file. unity_internals.h doesn't have C++ guards, and is included from unity.h from within C++ header guard block. Same approach is taken in this commit

UnityMainwhen test cases based on Unity fixture are defined in a .cpp file.unity_internals.hdoesn't have C++ guards, and is currently included fromunity.hfrom within C++ header guard block.I followed the same approach in
unity_fixture.hmoving it into the guarded block, to make the changes in this PR minimal.It would be slightly cleaner, although more intrusive, to add C++ guards to
unity_internals.hand keep it outside of the C++ guarded block in bothunity.handunity_fixture.h. Please let me know if you prefer this approach, I can update the PR.
