update_engine: Standarize mock/fake filenames.
Mock classes implement mostly MOCK_METHOD* methods used with gmock.
Those classes should be named with the prefix "Mock" in the class
name and "mock_" in the header filename.
Fake classes implement a working version of the interface they provide,
often with extra functionality to change their behavior. Those classes
should be prefixed with "Fake" in the class name and "fake_" in the
file name.
Other minor include order fixes are included in this patch.
BUG=None
TEST=Unittest still pass.
