winex11.drv: WM_SYSCOMMAND/SC_CLOSE should be posted not sent

[Dmitry Timoshkov]

Hello,

this patch fixes crash on exit reported in the bug #2918.

In DefWindowProc we already use PostMessage for WM_SYSCOMMAND/SC_CLOSE
in response to Alt+F4.

Changelog:
    winex11.drv: WM_SYSCOMMAND/SC_CLOSE should be posted not sent.
