libvirt_qemu_probes.stp stopped working after switching to a build that used --with-driver-modules. This was because the symbols listed int libvirt_qemu_probes.stp are no longer in $(bindir)/libvirtd, but are now in $(libdir)/connection-driver/libvirt_driver_qemu.so. This patch enhances dtrace2systemtap.pl (which generates the .stp files from .d files) to look for a new "module" setting in the comments of the .d file (similar to the existing "binary" setting), and to look for a --with-modules option. If the --with-modules option is set *and* a "module" setting is present in the .d file, the process name for the stap line is set to $libdir/$module If either of these isn't true, it reverts to the old behavior. src/Makefile.am was also modified to add the --with-modules option when the build calls for it, and src/libvirt_qemu_probes.d has added a "module" line pointing to the correct .so file for the qemu driver.
