fvp_utils.sh: include global fvp container related variables.

Include several FVP docker container related variables with the
intention to be the default values if run config snippets do not
explicitly provide them. Also, there are some minor chanes on the yaml
generation routine (gen_fvp_yaml) taking into account the new
introduced variables.
