Makefile: fix package file list if FOO_SUBDIR is set

If a package sets a FOO_SUBDIR (meaning its sources are not under
output/build/foo-123 but under output/build/foo-123/$(FOO_SUBDIR)), the
.files-list.txt file were also created under FOO_SUBDIR, due to which the
logic in the Makefile would not find it.

Change the instrumentation steps so that the file list is directly under the
package dir, ignoring the subdir.
