update_engine: UM: Move static member initialization to .cc file.
Using default initializers for these members in header files results in
multiple instantiations in different translation units and leads to link
errors when compiled (for example) with clang.
BUG=None
TEST=Builds fine w/ clang, passes unit tests.
