Merge bitcoin#12772: [CI]: bump travis timeout for make check to 50m

bc308ba [CI]: bump travis timeout for make check to 50m (Karl-Johan Alm)

Pull request description:

  The travis windows build sometimes times out on `make check`. Bump the timeout from 20 to 50 minutes.

  This is a short-term measure. We should figure out why the unit tests are slow in Wine.
