softmmu/memory: Pass ram_flags to qemu_ram_alloc_from_fd()
Let's pass in ram flags just like we do with qemu_ram_alloc_from_file(), to clean up and prepare for more flags. Simplify the documentation of passed ram flags: Looking at our documentation of RAM_SHARED and RAM_PMEM is sufficient, no need to be repetitive.
