[PATCH] make dcerpc python module compatible with pylint in py3

[Alexander Bokovoy]

Attached patch needs to come to 4.7.0 to have Samba python3 bindings
usable with pylint (Python linter). We missed dcerpc/__init__.py file
for py3 environment so it broke FreeIPA CI machinery now that we moved
to Python 3 completely.

Luckily, it is not a code change, just waf part.

I filed https://bugzilla.samba.org/show_bug.cgi?id=13030 for 4.7.0
backport. See details on a reproducer there.

We verified with Fedora builds that it indeed fixes the problem.

Subject: [PATCH] Install dcerpc/__init__.py for all Python environments

Also fix whitespace. We use tabs, not spaces in Python/waf code.
