examples/sslbackend: fix -Wchar-subscripts warning
With the `isdigit` implementation that comes with MSYS2, the argument is used as an array subscript, resulting in a -Wchar-subscripts warning. `isdigit`'s behavior is undefined if the argument is negative and not EOF [0]. As done in lib/curl_ctype.h, cast the `char` variable to `unsigned char` to avoid that. [0] https://en.cppreference.com/w/c/string/byte/isdigit Closes https://github.com/curl/curl/pull/4503
