Subject: [PATCH] vsftpd: fix build with gcc15

- add patch from fedora, fixing `setup_bio_callbacks` definition

Fixes build failure with gcc15:
```
ssl.c: In function 'ssl_accept':
ssl.c:493:3: error: too many arguments to function 'setup_bio_callbacks';
expected 0, have 1
  493 |   setup_bio_callbacks(p_ssl);
      |   ^~~~~~~~~~~~~~~~~~~ ~~~~~
ssl.c:37:13: note: declared here
   37 | static void setup_bio_callbacks();
      |             ^~~~~~~~~~~~~~~~~~~
ssl.c: In function 'ssl_session_init':
ssl.c:647:3: error: too many arguments to function 'setup_bio_callbacks';

  647 |   setup_bio_callbacks(p_ssl);
      |   ^~~~~~~~~~~~~~~~~~~ ~~~~~
ssl.c:37:13: note: declared here
   37 | static void setup_bio_callbacks();
      |             ^~~~~~~~~~~~~~~~~~~
ssl.c: At top level:
ssl.c:692:13: error: conflicting types for 'setup_bio_callbacks'; have
'void(SSL *)' {aka 'void(struct ssl_st *)'}
  692 | static void setup_bio_callbacks(SSL* p_ssl)
      |             ^~~~~~~~~~~~~~~~~~~
ssl.c:37:13: note: previous declaration of 'setup_bio_callbacks' with
type 'void(void)'
