gsdx: increase buffer to have crash in case of overflow 

Avoid a crash on Onimusha3 (PAL 60HZ)

In theory it will be better to find the root cause of overflow. I.e. somewhere in this
code below. Dirty rectangle is too big.

***********************************************************************
if(rowsize > 0 && offset % rowsize == 0)
{
    int y = GSLocalMemory::m_psm[psm].pgs.y * offset / rowsize;

    if(r.bottom > y)
    {
        GL_CACHE("TC: Dirty After Target(%s) %d (0x%x)", to_string(type),
                t->m_texture ? t->m_texture->GetID() : 0,
                t->m_TEX0.TBP0);
        // TODO: do not add this rect above too
        t->m_dirty.push_back(GSDirtyRect(GSVector4i(r.left, r.top - y, r.right, r.bottom - y), psm));
        t->m_TEX0.TBW = bw;
        continue;
    }
}
***********************************************************************

So as a temporary solution (that will likely stay for a couple of
years), buffers were increased.
