perf beauty: Introduce scrape script for 'clone' syscall 'flags' argument
It was using the first variation on producing a string representation for a binary flag, one that used the copy of uapi/linux/sched.h with preprocessor tricks that had to be updated everytime a new flag was introduced. Use the more recent scrape script + strarray + strarray__scnprintf_flags() combo. $ tools/perf/trace/beauty/clone.sh | head -5 static const char *clone_flags[] = { [ilog2(0x00000100) + 1] = "VM", [ilog2(0x00000200) + 1] = "FS", [ilog2(0x00000400) + 1] = "FILES", [ilog2(0x00000800) + 1] = "SIGHAND", $ Now we can move uapi/linux/sched.h from tools/include/, that is used for building perf to the scrape only directory tools/perf/trace/beauty/include.

-/**
- * struct clone_args - arguments for the clone3 syscall
- * @flags: Flags for the new process as listed above.
- * All flags are valid except for CSIGNAL and
- * CLONE_DETACHED.
- * @pidfd: If CLONE_PIDFD is set, a pidfd will be
- * returned in this argument.
- * @child_tid: If CLONE_CHILD_SETTID is set, the TID of the
- * child process will be returned in the child's
- * memory.
- * @parent_tid: If CLONE_PARENT_SETTID is set, the TID of
- * the child process will be returned in the
- * parent's memory.
- * @exit_signal: The exit_signal the parent process will be
- * sent when the child exits.
- * @stack: Specify the location of the stack for the
- * child process.
- * Note, @stack is expected to point to the
- * lowest address. The stack direction will be
- * determined by the kernel and set up
- * appropriately based on @stack_size.
- * @stack_size: The size of the stack for the child process.
- * @tls: If CLONE_SETTLS is set, the tls descriptor
- * is set to tls.
- * @set_tid: Pointer to an array of type *pid_t. The size
- * of the array is defined using @set_tid_size.
- * This array is used to select PIDs/TIDs for
- * newly created processes. The first element in
- * this defines the PID in the most nested PID
- * namespace. Each additional element in the array
- * defines the PID in the parent PID namespace of
- * the original PID namespace. If the array has
- * less entries than the number of currently
- * nested PID namespaces only the PIDs in the
- * corresponding namespaces are set.
- * @set_tid_size: This defines the size of the array referenced
- * in @set_tid. This cannot be larger than the
- * kernel's limit of nested PID namespaces.
- * @cgroup: If CLONE_INTO_CGROUP is specified set this to
- * a file descriptor for the cgroup.
- *
- * The structure is versioned by size and thus extensible.
- * New struct members must go at the end of the struct and
- * must be properly 64bit aligned.
