matchbox-desktop 0.9.1: fix segfault at startup and convert to new staging
matchbox-desktop 0.9.1: fix segfault at startup and convert to new staging

If matchbox-common is not present,matchbox-desktop segfault
  (the debugging was done with strace)
Also convert to new staging:
  I had packaged staging,removed the custom do_stage and got:
    staging/armv6-angstrom-linux-gnueabi/usr/include/matchbox-desktop $ ls
    mbdesktop.h  mbdesktop_item.h  mbdesktop_module.h  mbdesktop_view.h
  Thanks Tartarus for confirming me what to do in case of custom do_stage
