    sbin/hammer: Change fprintf/exit to err variants [2/2]
    
    Change
    fprintf(stderr, ...); exit(1);
    and
    perror(...); exit(1);
    to
    err(1, ...) or errx(1, ...);
    where possible for consistency.
    
    This commit is just conversion to err(3) variants.
    Messages themselves are not changed, except for removing
    strerror(errno) for err(3), and removing trailing \n,
    though err variants add program name in the messages.
    
    err(3) and variants are non standard BSD functions, but HAMMER
    userspace has been using BSD stuff aside from the existing
    err/errx. Also note that err(3) is available in Linux as well.
