Fix java AIDL properties to match C/C++

The C/C++ aidl properties use:
aidl: {
    local_include_dirs: [],
    include_dirs: [],
}

But the Android.bp file was expecting:
aidl_include_dirs: [],
export_aidl_include_dirs: [],

Update java AIDL support to match the C support, which is
also what the androidmk conversion tool is creating.

Test: m checkbuild
