DO NOT MERGE Remove *.aidl for parcelable declarations from srcs

When an AIDL file is listed in the srcs property, the build system
expects a Java file for the AIDL file even when the AIDL file is for a
parcelable declaration. Previously, the AIDL compiler generated an empty
Java file in that case, but with Iaa9c78c5df06afee165462db05c6dc6e11a1ba8a
that is no longer the case.

Therefore, removing two AIDL files for the parcelable declarations from
the srcs property.

Note that, in master branch (for R and beyond), we don't need to
filter-out such AIDL files because the build system expects a srcjar
file from AIDL files. This change is only for Q where the build system
change doesn't exist.
