bgo#315462 - Make GtkLabel deal with too-small height allocations gracefully

Previously we would always align the top of the text with the label's allocation-plus-padding.
However, this makes a single-line label inside a GtkButton look badly clipped when the button
has a smaller allocation than its requisition.  So, for single-line labels we respect the
alignment even if it doesn't fit within the label's allocation.  But for multi-line labels, we
give preference to showing the first line, to give the user some context.

* - Single-line labels appear in GtkButtons, and it is very easy to get them
* to be smaller than their requisition. The button may clip the label, but
* the label will still be able to show most of itself and the focus
* rectangle. Also, it is fairly easy to read a single line of clipped text.
* - Multi-line labels should not be clipped to showing "something in the
* middle". You want to read the first line, at least, to get some context.
