    There is no scrape script yet for those, but the warning pointed out we
    need to update the array with the F_LINUX_SPECIFIC_BASE entries, do it.
    
    Now 'perf trace' can decode that cmd and also use it in filter, as in:
    
      root@number:~# perf trace -e syscalls:*enter_fcntl --filter 'cmd != SETFL && cmd != GETFL'
         0.000 sssd_kcm/303828 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLK, arg: 0x7fffdc6a8a50)
         0.013 sssd_kcm/303828 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLKW, arg: 0x7fffdc6a8aa0)
         0.090 sssd_kcm/303828 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLKW, arg: 0x7fffdc6a88e0)
      ^Croot@number:~#
    
    This picks up the changes in:
    
      c62b758b ("fcntl: add F_DUPFD_QUERY fcntl()")
    
    Addressing this perf tools build warning:
    
      Warning: Kernel ABI header differences:
