lib/oe/package_manager.py: OpkgPM/DpkgPM fixes

This commit:
 * adds missing mark_packages() function for OpkgPM. This is needed to
 * manually change the packages installation status in the status file;
 * fix OpkgPM remove_packaging_data() issue;
 * fix OpkgPM handle_bad_recommendations() issue;
 * improve OpkgPM/DpkgPM mark_packages() regex pattern;
 * fix DpkgPM list_installed() problem;
 * fix DpkgPM _create_configs() problem: status file should not be
   truncated if it already exists/
