Skip features_macro Test in Offline Mode (#1034)

- [x] Skip the `features_macro` test in offline mode since it makes
calls to `create_single_kernel_helper_create_program` and fails when the
call doesn't return `CL_SUCCESS` which will happen when the offline
compiler fails to compile the kernel which is deliberately supposed to
fail compilation in this test.
