Since golang.org/x/sys/unix provides portable way to use uname(2) syscall, let's use it for all unix variants, removing the duplicated code from uname_*.go.

While at it:

  • remove uname_unsupported*.go (not used);
  • use unix.ByteSliceToString.

NOTE this also removes the public definition of struct Utsname. I am puzzled as to why it was exported as it is not (and was not) used by any public functions in this package, nor I was able to find any usage of kernel.Utsname (using sourcegraph).

Simplifying the Unix implementation, sure.

WRT removing the public Utsname symbol, c/storage is supposed to have a stable API, but with things like #1622 (and many others), that’s… not been consistently the case.

As I was not able to find any existing users of kernel.Utsname, this API breakage seems purely theoretical.
