testrunner: use structs with designated initialization to pass options (#4975) 

I need to add parameters to some `check()` functions in the tests and
things are already pretty messy with having to specify all the default
values - readability aside.

I found this on https://stackoverflow.com/a/49572324/532627 - apparently
the CC BY-SA license by StackOverflow allows the usage within GPL.
