Cygwin: pty: Discard CSI > Pm m sequence from native windows apps.

- If vim is started from WSL (Ubuntu) which is executed in pseudo
  console in mintty, shift key and ctrl key do not work. Though
  this issue is similar to the issue resolved by commit
  4527541ec6, that commit is not
  effective for this issue. This patch fixes the issue by discarding
  "CSI > Pm m" in fhandler_pty_master::pty_master_fwd_thread().
