CI: Specify cargo arguments instead of features in matrix

With an upcoming change the novendor feature will be deprecated and
should no longer be used. It will be replaced by building the library
without any features. To express that in CI, switch from having a
"features" argument to a more general "args", which will simply hold
--no-default-features for the case where no features are desired (but
for now no semantic change is made).
