Subject: vendor: adding in golang.org/x/sys/unix package

This commit adds in the golang.org/x/sys/unix package. This package
provides a low-level interface to unix syscalls. We will uses this
package instead of the built-in "syscall" package because the syscall
package is locked down (https://golang.org/pkg/syscall) and is not
exposing any new kernel functionality.

In fact, this is actually a patched version of the x/sys/unix package
pending review (first part: https://go-review.googlesource.com/c/37943).
The version included in this commit exposes all of the filesystem
encryption kernel interfaces to Go code.
