Sebastiaan van Stijn 95c0705164 make tests linux-only 
These tests were testing functionality that was only supported on
Linux, but stubbed for other platforms, so move them to a linux-only
file.

Sebastiaan van Stijn 22a9216d17 remove redundant build-tag comments 
- The "linux" build tags were redundant as they were in a _linux file
- The project already states that go1.10 is a minimum (and long obsolete,
  so unlikely to be used still).
- Format the remaining build-tags for current go versions.

This completes the migration from `syscall` --> `golang.org/x/sys/unix`
which was started in https://github.com/vishvananda/netns/pull/40:
> The syscall package is deprecated and no longer updated as per
https://golang.org/pkg/syscall/. Use the golang.org/x/sys/unix package
instead.

Tobias Klauser 52d707b772 Use golang.org/x/sys/unix instead of syscall 
The syscall package is deprecated and no longer updated as per
https://golang.org/pkg/syscall/. Use the golang.org/x/sys/unix package
instead, which also provides a wrapper for SYS_SETNS, so the syscall
number encoding depending on runtime.GOARCH can be dropped.

matte21 7109fa855b Remove useless setting of new netns from README.md 
Remove from the README.md example the instruction which explicitly sets
the newly created netns as the netns of the current OS Thread. The removed
instruction is not needed because the setting is implicitly done by netns.New().

Martynas Pumputis b8d862b06e Add go1.10 build constraint 
This prevents netns from being used on older Go runtimes on which it's
not safe to perform any state manipulations of a scheduling thread
(https://github.com/golang/go/issues/20676).

Yann Ramin be1fbeda19 Search kubepods for Docker containers 
When using Kubernetes with CNI and Docker, the cgroup entries are
dropped in yet another creative place. This adds yet another attempt
to locate the container within `kubepods`. All of this because there
are no named network namespaces created.
