- 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.

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().
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).
