mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

mdoc: order prologue macros consistently by Dd/Dt/Os

Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

The manpage describes the latest batch of changes, and especially the
runtime config was totally different before.

Lots of updates on the install process, detailing how to
install PicoBSD on hard disks and CDROM images, and on the
bootstrap sequence and the places where you can customise
a PicoBSD image.

Now if some of the -doc guys want to put this stuff in a nice
handbook page, that would be extremely useful!

Update the manpage to reflect reality (and what was already in -stable).
