    package_manager: don't race on a file when installing complementary packages
    
    PackageManager.install_complementary() uses WORKDIR/installed_pkgs.txt as a
    temporary file but if two tasks are executing for the same recipe which uses
    this file (e.g. bitbake my-image my-image:do_populate_sdk) then it's possible
    for the file to be overwritten or deleted.
    
    Instead of using a static filename, use tempfile to generate a unique name and
    ensure it is cleaned up when finished.
    
    Also move the glob generation/expansion earlier in the function as if there are
    no globs to install, we don't need to generate a package list.
