unix: fix Setfsuid and Setfsgid return values
...
setfsuid(2) and setfsgid(2) both return an int value that indicates the
previous fsuid or fsgid set. This change makes unix.Setfsgid() and
unix.Setfsuid() return these values too instead of returning only an
error.

unix: add support for linux/riscv64
...
Add syscall wrappers, error constants and types for linux/riscv64
Switch docker image to Ubuntu 18.10 in order to get qemu supporting
riscv64. Also set the uname release string for qemu to 4.15 (the first
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.
