Killed trailing spaces in group/host vars with fire.

Normally it's just a nitpick to not have trailing spaces on variables.
However, for some things like mac address, it really matters.
Bunches of buildhw's were failing ansibile because they were passing
"mac address " to linux-system-roles networking and ansible was going
'huh, nope, I can't find that mac address here at all'.
So, just blow all the tailing spaces away to avoid any other variables
that hit this.
