pylint: reland upgrade to 1.5.6

** WARNING: please do not revert this CL without checking with vapier@ first ***

We disable new warnings that are triggered in depot_tools to pylintrc.
So the lint output before & after this CL are mostly unchanged.  The
repos checked: depot_tools, src, and build.

Also update its deps along the way:
- Update astroid to 1.4.9.
- Drop now unused logilab.common.
- Import lazy_object_proxy 1.3.1.
- Import wrapt 1.10.11.

This should address the issue where some Chromium bots don't have the
lazy_object_proxy/wrapt python modules installed.  These have optional
C modules that we don't compile either as they have Python fallbacks.
