[ruby/openssl] Raise an exception if the IO object passed to SSLSocket isn't a file
SSLSocket#connect eventually calls `GetOpenFile` in order to get the underlying file descriptor for the IO object passed in on initialization. `GetOpenFile` assumes that the Ruby object passed in is a T_FILE object and just casts it to a T_FILE without any checks. If you pass an object that *isn't* a T_FILE to that function, the program will segv. Since we assume the IO object is a file in the `connect` method, this commit adds a `CheckType` in the initialize method to ensure that the IO object is actually a T_FILE. If the object *isn't* a T_FILE, this class will segv on `connect`, so I think this is a backwards compatible change.
