LOG: [lldb] Ensure that TestMemoryCache.py reads allocated memory (#151635)

The test reads 400 bytes of memory above the local variable. If the
stack is shallow, this can reach non-allocated space, resulting in a
test failure. The patch fixes the issue by reserving enough space in
the upper stack frame.
