perf tools fixes for v5.17: 3rd batch

- Fix double free in in the error path when opening perf.data from multiple
   files in a directory instead of from a single file.
 
 - Sync the msr-index.h copy with the kernel sources
 
 - Fix error when printing 'weight' field in 'perf script'.
 
 - Skip failing sigtrap test for arm+aarch64 in 'perf test'.
 
 - Fix failure to use a cpu list for uncore events in hybrid systems, e.g. Intel
   Alder Lake.
