[Xamarin.Android.Tools.Bytecode-Tests] Update for API-24 docs (#142)

The `ParameterFixupTests.XmlDeclaration_FixedUpFromDocumentation()` and
`ParameterFixupTests.XmlDeclaration_FixedUpFromApiXmlDocumentation()`
tests read a `java.util.Collection.class` file that contains no
parameter name information, and uses XML and/or "JavaDoc" HTML
documentation to ascertain the correct parameter names.

For better or worse, parameter names are *not* part of any Java ABI,
and thus can change over time.

Which is what happened here: these tests were originally written
against the Android documentation for API-18. Since then, the docs for
API-24 have *changed the parameter names* for the `Collection.add(E)`
method, changing the parameter name from `object` to `e`.

Update the expected paramater names when reading docs from
`$ANDROID_SDK_PATH` so that the API-24 names are expected.
