qapi-commands: De-duplicate output marshaling functions
gen_marshal_output() uses its parameter name only for name of the
generated function. Name it after the type being marshaled instead of
its caller, and drop duplicates.
Saves 7 copies of qmp_marshal_output_int() in qemu-ga, and one copy of
qmp_marshal_output_str() in qemu-system-*.
