    Remove fts sorting.  It was originally put there to copy files
    before directories since files (usually) are in the same cylinder
    group and subdirectories aren't.  However, this mostly changed with
    the new ffs dirpref algorithm in 2001.

    No sorting has two effects:
    1) copy appears to be somewhat faster (e.g. on my laptop cp'ing build
       objdir to tmpfs is 7% faster after the change)
    2) source file parameters no longer get randomly shuffled due to
       fts doing an unstable sort of them.  this means that
       "cp 1 2 3 4 dest/" will copy the files in that order instead
       of e.g. 3 4 1 2.
