[PATCH] Cygwin: console: Align the behaviour against signal with pty.

[Takashi Yano via Cygwin-patches]

- Currently, read() returns -1 with EINTR if the process is suspended
  by Ctrl-Z and resumed by fg command, while pty continues to read.
  For example, xxd command stops with error "Interrupted system call"
  after Ctrl-Z and fg. This patch aligns the behaviour with pty (and
  Linux).
