QMP is not available on user emulation; there is not monitor.
Besides, since commit a0e61807a3 ("qapi: Remove QMP events

qapi-commands-trace.h header in a user-emulation-only build.

Remove the QMP trace commands from qemu-user binaries.

Maybe this pattern deserves adding a variable similar to:

   have_monitor = have_system or have_tools or have_ga
