Various pages: Use .nf/.fi in SYNOPSIS

The majority of pages use .nf/.fi in SYNOPSIS, but there are
still many that don't and use .br to achieve newlines. Fix many
of those. This brings greater consistency to the pages, which
eases editing and may ease future scripted edits to the pages.

Many of these changes were script-assisted, with some additional
manual edits.
