sync curly braces markup, fix indent

Replace literal braces with .Brq, use lists, replace literal 'foo options'
with .Ar option ... and indent options where they belong.

This highlights config parser differences between daemons:
- dhcpleased: requires empty blocks, e.g. 'interface em0 {}' (Brq Op Ar option ...)
- rad:  lets you omit them, e.g.          'interface em0'    (Op Brq Ar option ...)
