Cygwin: console, pty: Fix segfault in child_info_spawn::worker().
- After the commit "Cygwin: pty, console: Fix handle leak which
occurs on exec() error.", startxwin cannot start X due to the
error "Failed to activate virtual core keyboard: 2". The problem
is access violation in the code retrieving the pgid of the ctty.
This patch fixes the issue.
