update_engine: Update libchrome APIs to r405848
The new libchrome has been ported from Chromium and some APIs have
changed. Make necessary changes at call sites.
Notable changes from libchrome:
- base::Bind() now explicitly disallows captures in lambdas (which was
never allowed in the style guide), so lambdas should now be written in
a way that take the captures as parameters.
Bug: 29104761
Test: All tests in update_engine_unittest pass on dragonboard-eng build
