gh-133597: Fix memory leak if error occurred in _sys_getwindowsversion_from_kernel32

[sergey-miryanov]

If GetFileVersionInfoW or VerQueryValueW fails inside _sys_getwindowsversion_from_kernel32 then allocated verblock not freed.

• Issue: Possible memory leak on error path in _sys_getwindowsversion_from_kernel32 #133597

I believe this PR may skip news.

FYI, Sergey, the CI fails due to the recent beta(3.14b1) release. I'll restart it later.

[sergey-miryanov]

Thanks! Yeah, I saw a possible fix #133599
