[ng] cleanup: merge '%compile_clean_files' in '%clean_files'

No need to keep them separated anymore.

* automake.in (%libtool_clean_directories): Delete.
(initialize_per_input): Don't reset it.
(handle_compile): Don't merge '%libtool_clean_directories' (after
proper editing) into '%clean_dirs'.
(handle_ltlibraries, handle_programs, handle_single_transform):
Update '%clean_dirs', rather than '%libtool_clean_directories'.
