dev-manual: Added new section on conserving disk space

For conserving disk space during builds, I added a new section
that tells how to add "rm_work" to your local.conf file.
This information was part of the original YP Quick Start
and was not carried forward into the new brief build
document.

+            To help conserve disk space during builds, you can add the
