Test status of packages

[fingolfin]

Status of "failing" package tests:

1. packagemanager: genuine failures in tst/PackageManager.tst:
   • already line 12 fails: RemoveDirectoryRecursively(Filename(Directory(dir), "bin")); results in Error, dirname must be a directory
   • next CompilePackage("curlInterface"); fails, but we get no hint as to why?
2. polycyclic: genuine failure (endless loop?)
3. recog: genuine failure

Also, yangbaxter sometimes fails, due to overrunning the timeout we set for the tests. Its runtime seem to fluctuate heavily, likely due to randomization?
