install: remove enlarging shared memory size

Because it needs communication protocol to deliver the frame buffer data
to swt skin, the frame buffer between swt skin and qemu was shared by shared memory.
The size of the buffer needs big size.(the size is calculated by width * height * color depth)
It caused performance issue.
Also the buffer was useless since the protocol was integrated by QT.
