Override Blacklight changed CSS to put .constraints-container back to…

… display:block

We had written some custom CSS for display:block that doesn't work when BL 7.20.0 changes to display:flex. The display:flex also causes some other display we find undesirable. projectblacklight/blacklight#2552

We'll just stick with display:block at least for now, although diverging from Blacklight CSS further increases possible maintenance risk.
