Cygwin: spawn: Make ch_spwan_local be initialized properly

The class child_info_spawn has two constructors: one without arguments
and one with two arguments. The former does not initialize any members.
Commit 1f836c5f7394 used the latter to ensure that the local ch_spawn
(i.e., ch_spawn_local) would be properly initialized. However, this was
insufficient - it initialized only the base child_info members, not the
fields specific to child_info_spawn. This led to the issue reported in
https://cygwin.com/pipermail/cygwin/2025-August/258660.html.

This patch introduces a new constructor to properly initialize member
variable 'ev', etc., which were referred without initialization, and
switches ch_spawn_local to use it. 'subproc_ready', which may not be
initialized, is also initialized in the constructor of the base class
child_info.
