* Avoid using ${...} for shell variables (since they could be
expanded as bitbake variables if present)
* Use files-in-package.txt rather than files-in-<packagename>.txt; the
file is already in a subdirectory named with the package name and this
naming is consistent with that of files-in-image.txt.
