Much nicer than the yucky original ;-)

Why do you need this memcpy in the first place? Isn't ceil already
a NUL terminated string unlike the original code that points into a
part of the prefix_list string? IOW, why not
normalize_path_copy(buf, ceil);
or something?
Can normalize_path_copy() overflow buf[PATH_MAX+1] here (before or
after this patch)?
