Alexandre Ghiti dc04a00b3c riscv: Adjust mmap base address at a third of task size
[ Upstream commit ae662eec8a ]

This ratio is the most used among all other architectures and make
icache_hygiene libhugetlbfs test pass: this test mmap lots of
hugepages whose addresses, without this patch, reach the end of
the process user address space.
