build: don't lose probes.o files

The previous patch fixed an incremental build, but missed that on
a fresh checkout, we now have nothing left that stops make from
nuking libvirt_qemu_probes.o.

* src/Makefile.am ($(libvirt_driver_qemu_la_SOURCES)): Delete,
since this variable is empty.
(.PRECIOUS): Add %_probes.o, so they don't get nuked as an
intermediate by-product after creating %_probes.lo.
