lakitu_defconfig: Bumping CONFIG_ARCH_MMAP_RND_BITS down to 31 bits

This change is necessary to avoid issues where mapping overy memory that
certain programs, such as the go toolchain, depend on. It's worth
noting that chrome os had this problem before and have made this change
as well to accomodate the go toolchain.
