testsuite: filter out warning noise for CWE-1341 test
The case file-CWE-1341-example.c checkes [CWE-1341](`double-fclose`).
While on some systems, besides [CWE-1341], a message of [CWE-415] is
also reported. On those systems, attribute `malloc` may be attached on
fopen:
```
# 258 "/usr/include/stdio.h" 3 4
extern FILE *fopen (const char *__restrict __filename,
const char *__restrict __modes)
__attribute__ ((__malloc__)) __attribute__ ((__malloc__ (fclose, 1))) ;
or say: __attribute_malloc__ __attr_dealloc_fclose __wur;
```
See (PR analyzer/108722) for future fix in the analyzer.
This workaround patch adds -Wno-analyzer-double-free to this case.
