• unify ksh_dup2() usage, use bool where appropriate

Browse Source 
• apply diff from mirbsdksh-1.11:
  #ifdef DUP2_BROKEN
  /* Ultrix systems like to preserve the close-on-exec flag */
  ‣ XXX we do #ifdef __ultrix here (imake-style) instead of mirtoconfing it
    (but does anyone know of any other OS with the same problem? plus we’d
    see it as we now know the symptoms)
• remove ultrix Build.hs warn=' but might work…' in the hope it DOES
