LOG: [SystemZ] Add header guard macros to vecintrin.h (#129170)

Add header guard macros to clang/lib/Headers/vecintrin.h. Found while
compiling the latest numpy with clang 19 on s390x which ends up
including vecintrin.h twice. The gcc version of this file has header
guards so numpy compiles fine with gcc.
