test: delete simple/test-process-active-wraps

This test currently fails when run on machines without
IPv6 enabled. Futher it was delete in io.js under
3143d732f6 as the test
was known to have problems across platforms and
releases.

The existing test was hard to understand so I wrote
a new version but then found exactly what was
reported in the io.js pull request.  Behaviour varies
across platforms such that writing a solid test would
either be infeasible or test so little that
it does not seem to make sense to keep it.
