nm: Change layout of file chooser dialog

GTK4 does not support buttons at the bottom, so we put them in a header
bar, which is the preferred layout by current desktop environments. And
while it doesn't look ideal on older desktops, it also works with GTK3
and changing it avoids having to maintain multiple UI files.

Note that this layout is not supported by glade, so we generally can't
use it to edit the GUI anymore (it also doesn't support GTK4 in general).
