[OE-core] [PATCH] package_manager: Fix Argument list too long

[Ricardo Ribalda Delgado]

Function buildhistory_list_installed_image fails with error "Argument
list too long". This patch uses a temporal file to pass the package list
to opkg-query-helper.py

File: '/var/lib/jenkins/jobs/qt5022-cesium/workspace/repo/yocto/meta/lib/oe/package_manager.py', lineno: 421, function: list

     0419:                                                 (output, opkg_query_cmd),
