Add `compatibility-tradefed` for `libincident_test`

All of a test's dependencies should be explicitly declared in the Soong
build module to enable infrastructure features that ensure correctness
and optimize runtime.

The `FilePusher` class which is defined in `compatibility-tradefed` is
required because the corresponding TF test config has a target preparer
that uses the class and its specific option, `append-bitness`.

Note that we would not normally need to add `compatibility-tradefed` to
a test that's part of a test suite (e.g. CTS, etc) since the dependency
is implicit. It is required in this case, however, because the test is
not part of any suite.
