Travis: build Subsurface AppImage against Qt 5.12

For this we need our own hand crafted trusty container with Qt 5.12,
including QtWebKit and an updated cmake and libdbus, as well as already
build googlemaps plugin, grantlee and libgit2.

At the same time stop uploading the Subsurface AppImage in the
traditional trusty build.
