setup: conditionalize access to `sys.dllhandle` when building extensions

This code is only run on Windows, and was crashing PyOxidizer when running in
`setup-py-install` mode.  Now an oxidized binary can be built by simply pointing
to setup.py.

Something is slightly different now that it's not being built from a virtualenv.
Previously, `hg version` could print to the screen, but now it aborts saying
"Incorrect function".  But I can see the output if redirected to a file, and
it's not complaining about missing C extensions, so I think those are loading
now (unlike from the virtualenv).  The interesting this about this incorrect
function output is that it failed when initially built.  I then went back and
did a `make clean` and `make local` with py3 and then py2 to ensure I didn't
break the existing code.  At that point I ran the oxidized executable again and
it was able to print to the screen normally!  So I ran `pyoxidizer build` again,
it only output the following, and then running the executable failed to output
again:

are merging, unlike :local and :other
