perf tools fixes for v5.18: 3rd batch 

- Fix header include for LLVM >= 14 when building with libclang.
 
 - Allow access to 'data_src' for auxtrace in 'perf script' with ARM SPE perf.data
   files, fixing processing data with such attributes.
 
 - Fix error message for test case 71 ("Convert perf time to TSC") on s390, where
   it is not supported.
