configs: Add /chosen/stdout-path to riscv/fs_linux.py fdt
Adding this property makes the console work when booting a FreeBSD image.
Without this property the serial port will have all the output, but
FreeBSD will not use it as the default system console and therefore it
is not possible to send any input on the console.
