roots_rpm: Enable installation of recommended packages
Within RPM there is a field called "Suggests". This filed behaves like
"Recommends" does in ipk. So we write out the packages using the Suggests
field with the Poky 'Recommends' values... and then use the arbitrary tags to
capture the Poky 'Suggests' within a new "Recommends" tag.
Slightly confusing, but the end result is a functioning install.
Also some performance enhancements were add at the same time.
