chromeos-dbus-bindings: Inline some of named constants in tests

In order to make tests more readable and maintainable, removed named
constants and use string literals in their place. Since pretty much all
of these constants were used only once in a test, there is no benefit
in creating a constant, but it makes it difficult to read the test and
add new conditions/expectations.

BUG=None
