Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=53971

On Windows processes sometimes start during test_services_exe() so that
the size returned by the first NtQuerySystemInformation() is no longer
sufficient for the second call.

It looks like there was a change on the websocket test server that causes our
send operations to block. Reducing the size of the send buffer works around the
test failures. The tests still succeed on Windows, which suggests that native
sends large buffers in smaller chunks.

No longer used since e164b8ce.

GCC 12 complains about accessing a too small object.

In function 'test__AdjustPointer',
    inlined from 'func_msvcr90' at wine/dlls/msvcr90/tests/msvcr90.c:2515:5:
wine/dlls/msvcr90/tests/msvcr90.c:1556:30: warning: array subscript 30 is outside array bounds of 'void[8]' [-Warray-bounds]

      |                 ~~~~~~~~~~~~~^~~~~~~~~

Since we're only checking the addresses and not the underlying objects,
use uintptr_t instead of pointers.
