stub: Fix build failure with --enable-user --disable-system --enable-tools

Configuring "--enable-user --disable-system --enable-tools" causes the
build failure with the following information:

/usr/bin/ld: libhwcore.a.p/hw_core_qdev.c.o: in function `device_finalize':
/qemu/build/../hw/core/qdev.c:688: undefined reference to `qapi_event_send_device_deleted'
collect2: error: ld returned 1 exit status

To fix the above issue, add qdev.c stub when build with `have_tools`.

With this fix, QEMU could be successfully built in the following cases:
 --enable-user --disable-system --enable-tools
 --enable-user --disable-system --disable-tools
 --enable-user --disable-system
