arm64: fix COMPAT_SHMLBA definition for large pages ARM glibc uses (4 * __getpagesize()) for SHMLBA, which is correct for 4KB pages and works fine for 64KB pages, but the kernel uses a hardcoded 16KB that is too small for 64KB page based kernels. This changes the definition to what user space sees when using 64KB pages.
