ci: use ccache also in the mingw cross build

This is one of these two line changing commits one just have to love.
Using ccache also for the mingw builds got a amazing speedof for the
cross build as well.

In my, simple, testing I could reduce the build time on Travis from 18m
to 6m when rebuilding the same rev, thus a 100% cache hit rate. In real
life this would be less of an improvement but reducing the build time in
half is kind of realistic I think. Thanks to Marcel to bringing the idea
up.
