NetBSD uses sysctl with struct clockinfo to get clock rate information
from the kernel. Add type Clockinfo and the SysctlClockinfo function
to query this information.

This will be used in github.com/tklauser/go-sysconf to get _SC_CLK_TCK
on NetBSD.

If a system has the ability to disable some cores, as on
ppc64 with the ppc64_cpu command, then TestSchedSetaffinity will
fail if the CPUset passed to Setaffinity includes one that has
been disabled.

This adds a check to use values from the oldMask, which are the valid
cores returned from Getaffinity, to pass to Setaffinity.

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.

On linux/ppc64{,le} the SYS_SYNC_FILE_RANGE2 syscall is used to
implement SyncFileRange. This syscall has a different argument order
than SYS_SYNC_FILE_RANGE. Apart from that the implementations of both

with the correct argument order.
