[gnome-continuous-yocto/gnomeostree-3.28-rocko: 5818/8267] package_ipk/deb: Tweak functions for better cleanup and layout

[Emmanuele Bassi <ebassi src gnome org>]

    package_ipk/deb: Tweak functions for better cleanup and layout
    
    This uses more modern formatting to handle the lockfiles and control
    file cleanup with try/finally, taking advantage of the previous
    extra indentation.
    
    (From OE-Core rev: 9cd7c2631b0840a57b9ed6c201bcb4fc80094f71)
