RFR: 8277016: Use blessed modifier order in httpserver

[Magnus Ihse Bursie]

I ran bin/blessed-modifier-order.sh on source in jdk.httpserver. This scripts verifies that modifiers are in the "blessed" order, and fixes it otherwise. I have manually checked the changes made by the script to make sure they are sound.
