Update to domoticz spk&cross (rev 1801)

Boost patch did not seem to be necessary anymore, so removed
updates to Makefiles/PLIST of cross and spk for rev 1801
dsm-control.sh updated to correctly start/stop/status domoticz
installer.sh updated to create a /var directory
Please use the same as above:

    @mkdir -p $(STAGING_INSTALL_PREFIX)/bin
    @$(RUN) install -m 755 domoticz $(STAGING_INSTALL_PREFIX)/bin/
    [...] your other stuff

You can also use `cp -R` instead of `tar`, less cryptic.
