tools headers: Sync uapi/linux/prctl.h with the kernel source
To pick up the changes in these csets:
5ca243f6e3c30b97 ("prctl: add arch-agnostic prctl()s for indirect branch tracking")
28621ec2d46c6adf ("rseq: Add prctl() to enable time slice extensions")
That don't introduced these new prctls:

$ tools/perf/trace/beauty/prctl_option.sh > after.txt

That now will be used to decode the syscall option and also to compose
filters, for instance:

This addresses these perf build warnings:
Warning: Kernel ABI header differences:
diff -u tools/perf/trace/beauty/include/uapi/linux/prctl.h include/uapi/linux/prctl.h
Please see tools/include/uapi/README for further details.
