Previously when hybris-libsensorfw-qt5 is installed it brings sensorfw-qt5 and hybris-libsensorfw-qt5-configs
packaging in. The sensorfw-qt5 package then also takes in the sensorfw-qt5-configs which isn't really needed
with the hybris side. This patch makes the sensorfw-qt5-configs not to be installed when hybris-libsensorfw-qt5-configs
is there.

[packaging] Fix config packaging a bit to exclude not needed parts.
