Attached patch hasn't been tested, yet.
The trigger stuff can be simplified :-)
And no need to distinguish different triggers until you need to.

You need to activate the trigger also by installing the package
providing the trigger either with an explicit dpkg-trigger in the
postinst or by just running the trigger in in the postinst.

If qgis-providers-common triggers something that is not being awaited
for (because qgis-providers is not yet unpackaged or configured), the
trigger is lost (well, it triggered nothing, so nothing to do).

No need to, and if the directory is rather dynamic, not a good idea.
