[YAML] - Teach yaml2obj/obj2yaml to work with numeric relocation values.
That may be useful if we want to produce or parse object containing
broken relocation values using yaml2obj/obj2yaml.
Previously that was impossible because only enum values were parsed
correctly, this patch allows to put any numeric value as a
relocation type.
