Fix possible segfault with 0x0 shared opcache base
Moving the minimum base of the shared opcache memory to the second huge page to avoid a possible 0x0 base, which may cause all sorts of segfaults.
This is not a problem on most systems which have a mmap_min_addr which is non-zero, but e.g. WSL1 doesn't have a minimum mapping address.
