Replace brillo::make_unique_ptr with base::MakeUnique/base::WrapUnique.

base::MakeUnique mimics std::make_unique and is preferred over
brillo::make_unique_ptr (which is identical to base::WrapUnique).
brillo::make_unique_ptr will eventually be deprecated and removed as its
functionality is well covered by base::MakeUnique and base::WrapUnique.

BUG=chromium:704644
TEST=Run unit tests.
