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.
