In make, soong_config_set uses an $(eval) to set it's value, expanding
the value of the soong config variable _before_ evaluating the value.
Because of this, make will strip trailing whitespace like it does on
regular assignments.
Make rbcrun match this behavior.

dict(**h[0]) was only copying the top level dictionary
object, but not any other dictionaries/lists inside of
it. This was causing us to not find all the changes to
variables the board configuration was making, and so
some variables were not included in the output.
