tools headers UAPI: Sync linux/perf_event.h with the kernel sources
To pick the trivial change in:
ddecd22878601a60 ("perf: uapi: Document perf_event_attr::sig_data truncation on 32 bit architectures")
Just adds a comment.
This silences this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/perf_event.h' differs from latest version at 'include/uapi/linux/perf_event.h'
