    kldxref: do not error out if specified path is not directory, for -d mode
    
    kldxref(8) is the only tool that can dump FreeBSD kernel module
    metadata, with the -d option. But the command line requirements for that
    are inconvenient, since parser requires that argv[1] is a directory
    containing whole set of modules to generate xref file.
    
    For -d, allow argv[0] to be a regular file, now it is possible to do e.g.
       $ kldxref -d /boot/kernel/ufs.ko
    to see only ufs.ko metadata.
