This change is needed to support building gvisor for Fuchsia, which uses
Chromium's GN build system; at the time of writing, Fuchsia's Go support
does not include explicit enumeration of files, assuming instead that Go
binaries are always built from all Go source files in a given package.
Rather than extending Fuchsia's Go support, it is easier simply to
extract a separate package here.
