riscv: Select HAVE_ARCH_USERFAULTFD_MINOR

This allocates the VM flag needed to support the userfaultfd minor fault
functionality. Because the flag bit is >= bit 32, it can only be enabled
for 64-bit kernels. See commit 7677f7fd8be7 ("userfaultfd: add minor
fault registration mode") for more information.
