[PULL 01/49] stubs: avoid duplicate symbols in libqemuutil.a

[Paolo Bonzini <pbonzini@redhat.com>]

qapi_event_send_device_deleted is always included (together with the
rest of QAPI) in libqemuutil.a if either system-mode emulation or tools
are being built, and in that case the stub causes a duplicate symbol
to appear in libqemuutil.a.

Add the symbol only if events are not being requested.
