qapi: Restrict balloon-related commands to machine code

Only qemu-system-FOO and qemu-storage-daemon provide QMP
monitors, therefore such declarations and definitions are
irrelevant for user-mode emulation.

Restricting the balloon-related commands to machine.json pulls less
QAPI-generated code into user-mode.

+# @balloon:
+#
+# Request the balloon driver to change its balloon size.
+#
+# @value: the target logical size of the VM in bytes
+#         We can deduce the size of the balloon using this formula:
+#            logical_vm_size = vm_ram_size - balloon_size
+#         From it we have: balloon_size = vm_ram_size - @value
+#
+# Returns: - Nothing on success
+#          - If the balloon driver is enabled but not functional because the KVM
+#            kernel module cannot support it, KvmMissingCap
+#          - If no balloon device is present, DeviceNotActive
+#
+# Notes: This command just issues a request to the guest.  When it returns,
+#        the balloon size may not have changed.  A guest can change the balloon
+#        size independent of this command.

+# <- { "return": {} }
+#
+# With a 2.5GiB guest this command inflated the ballon to 3GiB.
