bits/syscall.h: add __NR_fchmodat2 from linux v6.6

the linux fchmodat syscall lacks a flag argument that is necessary to
implement the posix api, see

  linux commit 09da082b07bbae1c11d9560c8502800039aebcea
  fs: Add fchmodat2()

  linux commit 78252deb023cf0879256fcfbafe37022c390762b
  arch: Register fchmodat2, usually as syscall 452
