Add syscall wrappers, error constants and types for linux/riscv64

Switch docker image to Ubuntu 18.10 in order to get qemu supporting

Linux kernel version with riscv64 support), because otherwise running
the generating C program in mkerrors.sh on a host with an older kernel
would fail with a "FATAL: kernel too old".

Note that linux/riscv64 is currently only usable using gccgo.

On linux/ppc64{,le} the SYS_SYNC_FILE_RANGE2 syscall is used to

than SYS_SYNC_FILE_RANGE. Apart from that the implementations of both

with the correct argument order.
