Etienne PerotandgVisor bot 0620c3b638 cpuid: Initialize hostFeatureSet only when it's needed.
This moves the initialization of `cpuid.hostFeatureSet` out of package-level
`init` and instead moves it to an explicit `cpuid.Initialize()` function.

On AMD64, this saves about 512KiB of heap memory that would otherwise always
be live.

Ayush RanjanandgVisor bot a9441aea27 [op] Replace syscall package usage with golang.org/x/sys/unix in pkg/.
The syscall package has been deprecated in favor of golang.org/x/sys.

Note that syscall is still used in the following places:
- pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities
  are not yet available in golang.org/x/sys.
- syscall.Stat_t is still used in some places because os.FileInfo.Sys() still
  returns it and not unix.Stat_t.

Updates #214

Michael PrattandgVisor bot df5d377521 Remove go_test from go_stateify and go_marshal
They are no-ops, so the standard rule works fine.

We have been unnecessarily creating too many savable types implicitly.
