c6a3a81d19 scripts: check duplicated syscall number in syscall table
Currently, syscall{hdr,tbl}.sh sorts the entire syscall table, but you
can assume it is already sorted by the syscall number.

The generated syscall table does not work if the same syscall number
appears twice. Check it in the script.

b9da928abf scripts: add generic syscallhdr.sh
Most of architectures generate syscall headers at the compile time
in a similar way.

As of v5.11-rc1, 12 architectures duplicate similar shell scripts:

  $ find arch -name syscallhdr.sh | sort
  arch/alpha/kernel/syscalls/syscallhdr.sh
  arch/arm/tools/syscallhdr.sh
  arch/ia64/kernel/syscalls/syscallhdr.sh
  arch/m68k/kernel/syscalls/syscallhdr.sh
  arch/microblaze/kernel/syscalls/syscallhdr.sh
  arch/mips/kernel/syscalls/syscallhdr.sh
  arch/parisc/kernel/syscalls/syscallhdr.sh
  arch/powerpc/kernel/syscalls/syscallhdr.sh
  arch/sh/kernel/syscalls/syscallhdr.sh
  arch/sparc/kernel/syscalls/syscallhdr.sh
  arch/x86/entry/syscalls/syscallhdr.sh
  arch/xtensa/kernel/syscalls/syscallhdr.sh

My goal is to unify them into scripts/syscallhdr.sh.
