tools headers UAPI: Sync sched.h with the kernel
To get the changes in:
ef2c41cf38a7 ("clone3: allow spawning processes into cgroups")
Add that to 'perf trace's clone 'flags' decoder.
This silences this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/sched.h' differs from latest version at 'include/uapi/linux/sched.h'
