migration-test: Clean up string interpolation into QMP, part 2

Browse source 
Leaving interpolation into JSON to qmp() is more robust than building
QMP input manually, as explained in the recent commit "tests: Clean up
string interpolation into QMP input (simple cases)".

migrate() interpolates members into a JSON object.  Change it to take
its extra QMP arguments as arguments for qdict_from_jsonf_nofail()
instead of a string containing JSON members.

Bonus: gets rid of a non-literal format string.  A step towards
compile-time format string checking without triggering
-Wformat-nonliteral.
