When a recent build of mongod crashes during C Driver Evergreen tests it saves a minidump file in c:/mongodb/bin (on Windows), which is outside the working directory. Therefore we don't save that file anywhere it's accessible afterward. Let's either install the downloaded MongoDB within the working directory on Windows, or if tests fail search for a .mdmp file in c:/mongodb/bin and move it to the working directory before uploading the working directory at the end of the test.
