`FIO32-C`:  enhance the query to support secure `fopen` usage pattern

### Affected rules
 - FIO32-C

### Description

Currently the implementation simply checks that the filename used in a call to `fopen` is not tainted.
However, the rule requires that certain OS-supported dynamic checks are present in the code.
We'd like to enhance this query to support some usage pattern that would allow it to be excluded from being checked.
