cmd/internal/osinfo: use unix.ByteSliceToString

The golang.org/x/sys/unix package is already imported for Utsname and
Uname. Use ByteSliceToString from that package as well to replace the
locally defined utsString helper which serves the same purpose and
matches ByteSliceToString's implementation.
