Define NR_name_to_handle_at catchall for other architectures.

    The name_to_handle_at syscall number will be filled in automatically
    for most more common architectures (x86, arm, powerpc) but it is not
    for mips or sh or the like.

    As a catch-all, default to the only value for __NR_name_to_handle_at
    found in modern kernels (include/uapi/asm-generic/unistd.h).  This
    prevents a build error for this architectures.
