perf tools fixes for v6.10: 2nd batch 

- Update copies of kernel headers, which resulted in support for the new
   'mseal' syscall, SUBVOL statx return mask bit, RISC-V and PPC prctls,
   fcntl's DUPFD_QUERY, POSTED_MSI_NOTIFICATION IRQ vector, 'map_shadow_stack'
   syscall for x86-32.
 
 - Revert perf.data record memory allocation optimization that ended up
   causing a regression, work is being done to re-introduce it in the
   next merge window.
 
 - Fix handling of minimal vmlinux.h file used with BPF's CO-RE when
   interrupting the build.
