Subject: ref-manual, yocto-project-qs, poky.ent: Fixed CentOS essentials

Fixes [YOCTO #10854]

I added extra "yum" commands and a make command to deal with
some essential packages needed for CentOS distribution.  These
packages were missing.

(From yocto-docs rev: 38ac6cf0165f7dd7bbfd583e218b6948dafae29c)
