Switch to custom deleter type for unique_ptr

This prevents the error:

 src/parser/exec-checker/src/exec_checker.cc:202:42: error: ignoring attributes on template argument 'int (*)(FILE*)' [-Werror=ignored-attributes]
 202 |   std::unique_ptr<FILE, decltype(fclose)*> fp_auto(fp, fclose);
     |                                          ^
