build: add $(STAGING_DIR) and $(BIN_DIR) preparation to target and package subdir compile dependencies

In a pristine build, these directories are created as dependencies of
the tools subdir compile, however this step never runs when the tools
compile stamp already exists. Since commit ed6ba2801c0a ("tools: keep
stamp file in $(STAGING_DIR_HOST)"), this will happen after `make clean`:
$(STAGING_DIR) has been deleted, but the tools stamp still exists, so
the next build will fail because $(STAGING_DIR) has not been set up
correctly.

Fix builds after `make clean` by adding the preparation as dependencies
for the target and package directories as well.

Fixes: ed6ba2801c0a ("tools: keep stamp file in $(STAGING_DIR_HOST)")
