[gnome-software: 5/6] rpm-ostree: Use the thread-default main context when blocking

[Philip Withnall <pwithnall src gnome org>]

    rpm-ostree: Use the thread-default main context when blocking
    
    Rather than the global default main context (which belongs to the main
    thread). Iterating the global default main context can lead to
    deadlocks, or code executing on the wrong thread (for example, UI events
    being run in the rpm-ostree worker thread).
