fuzzy tester: Cache information about build results.

We remember the information whether a clean build succeeded. This
enables us to skip potentially expensive verification builds as well as
finding a usable start commit.
Note: This can lead to false positives or negatives if qbs or the build
environment have changed in a way that leads to a formerly succeeding
build failing or vice versa; however, this should be rare and easily
spottable.
