Cygwin: console: Align the behaviour against signal with pty.
- 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).
