move CI sanitizier, clazy, coverage builds to cmake (#926)

* switch linux CI extra_tests and coverage builds to cmake.

* add ninja to linux coverage install list

* add qt serial for coverage build

* add webengine for coverage build

* actually fail when ubsan finds an error!

* avoid divide by zero error in kml writer.

* teach camke that the check target uses the console.

this lets the test output show up as the tests run instead of
delaying it all until the end.
