libssh: fix 64-bit printf mask for mingw-w64 <=6.0.0

Fixing (dl-mingw, CM 6.4.0-i686 (mingw-w64 5.0.0) schannel !unity):
```
lib/vssh/libssh.c: In function 'myssh_in_SFTP_QUOTE_STATVFS':
lib/vssh/libssh.c:573:31: error: ISO C does not support the 'I' printf flag [-Werror=format=]
     char *tmp = curl_maprintf("statvfs:\n"
                               ^~~~~~~~~~~~
lib/vssh/libssh.c:573:31: error: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'uint64_t {aka long long unsigned int}' [-Werror=format=]
lib/vssh/libssh.c:573:31: error: ISO C does not support the 'I' printf flag [-Werror=format=]
[...]
```

mingw-w64 <=6.0.0 define `PRIu64` like this:
```
./inttypes.h:#define PRIu64 "I64u"
```
