Remove srcs_lib_whitelist_dirs

This change removes srcs_lib_whitelist_dirs which was used to let
droiddoc to know the base directories for the AIDL/Java source files.
Instead, the base directories are given via the path property of the
filegroup modules.

This change also includes a fix that the base directories from all
filegroup modules listed in srcs are used as the import paths for the
AIDL compiler. This removes the need to have aidl.[local_]include_dirs.
