`path_from_tracker_dir()` shouldn't return `NULL` since the functions
calling it do not check for a `NULL` return value.

Reported in https://github.com/pop-os/gnome-control-center/issues/149

While the code was using the pattern to cancel the operation, it was
still resolving the user_data pointer even in the case the operation has
been cancelled.

Fix this by simply moving the initialization.

The empty search state looks out-of place due to it being nested inside
a listbox. This is because we can only detect empty states through
gtk_list_filter_func().

Refine it by making the empty search placeholder a child of the main stack.
Introduce an additional helper function to detect when all the listbox
rows would be hidden by the filter.

By default info-overview panel shows the Gnome logo from a static
resource, currently every distro patches this component to show their logos

info-overview panel could use `/etc/os-release` file to fetch the OS logo
instead this static resource

This makes scaling work e.g. on the Librem 5's built-in display which
has a 720x1440 resolution. It's scaled to 200% by default so currently
hitting the 100% button makes it scale to 100% but then the 200% button
vanishes due to assumed too small resultion. Fix that by allowing for
360x720 as well.

I don't really have a capacity for this already...
