perf-tools fixes and updates for v6.19

A number of small updates:
 
  - skip building BPF skeletons if libopenssl is missing
  - a couple of test updates
  - handle error cases of filename__read_build_id()
  - support NVIDIA Olympus for ARM SPE profiling
  - update tool headers to sync with the kernel
