golang: Don't keep test programs inside golang/ dir

Python adds dirname of run program to sys.path . This way when runs it can import modules located under golang/
just by their name. Until now this was not noticed, but in the next
patch we are going to add golang.time module and if test program is run
with golang/ in sys.path just plain `import time` won't import time from
stdlib and instead import time from golang/ .

Such behaviour can be mitigated by doing `from __future__ import
absolute_import` and we do that, including in
(see 81dfefa0 "*: __future__ += absolute_imports; Use unified __future__
everywhere"). However that does not prevent modules - even modules from
stdlib - who are doing `import time` and not doing future
absolute_import to import golang's time instead of stdlib. For example
on PyPy2 threading imports time and then the test breaks:

  Traceback (most recent call last):
    File "/home/kirr/src/tools/go/pygolang/.tox/pypy-thread/site-packages/golang/", line 24, in <module>
      from golang import go, chan
    File "/home/kirr/src/tools/go/pygolang/.tox/pypy-thread/site-packages/golang/", line 38, in <module>
      import inspect, threading, collections, random, sys
    File "/usr/lib/pypy/lib-python/2.7/", line 15, in <module>
      from time import time as _time, sleep as _sleep
    File "/home/kirr/src/tools/go/pygolang/.tox/pypy-thread/site-packages/golang/", line 30, in <module>
      from golang import go, chan, select, default, nilchan, panic
  ImportError: cannot import name 'go'

-> Move the test program into a directory different from golang/ to
avoid this trap.
