David Ahern be9cefe796 selftests: rtnetlink: use internal netns switch for ip commands ...

'ip' can switch network namespaces internally and then run a given
command relative to that namespace without the need to fork and exec
another ip instance. Update all references of the form:
    ip netns exec "$testns" ip ...
to
    ip -netns "$testns" ...
