After the commit 93508e5bb841, the access permissions argument passed
to open_shared() is ignored and always replaced with (FILE_MAP_READ |
FILE_MAP_WRITE). This causes the weird behaviour that sshd service
process loses its cygwin PID. This triggers the failure in pty that
transfer_input() does not work properly.
This patch resumes the access permission settings to fix that.
