dev-manual: Edits to "Enabling System Services" section.

Browse Source 
Applied review comments from Paul Eggleton to the section that is
part of the "Writing a New Recipe" section.  I changed the title
of the section and applied some rewordings to better reprepresent
exactly what sysvinit and systemd really are (managers).

(From yocto-docs rev: 95c3ed5b7d1ace08828baacc8401e1ea5d96a06e)
