Configure fixes

Packages (ctetgen in particular should not use self.installDirProvider.installSudo directly)

Check that user has write permission on --package-prefix-hash otherwise generate very useful error message

When checking write permission for --prefix print the errors that appear so one has a better understanding of why the permissions are not available

Fix move_configure_log() it did not create one of the intermediate directories and hence would crash if used
