pkg/entrypoint: clean after running tests

TestEntrypointer_OnError leaves some created file behind :
`termination`. This change does 2 things:

- Use a temporary file in order to not create anything in the current
directory
- Make sure we remove the file once the test is done

This also uses a temporary file for TestEntrypointer
