fix keyboard offset in win11 25h2

[jhl337]

In Windows 11 25H2, this offset has changed to 0x3800(14336).
If still uses 0x3808, the function is_key_down will returns the incorrect result.

OS Version: Windows 11 25H2 (Internal: 26200.7705)

For example, if you use is_key_down to detect the state of the 0x01 key, it actually returns the status of the 0x20 key instead.

This will however break the version that required 0x3808 🙈

We really need a rework of this, ideally based on some proper sigscanner using goblin or pelite.
