common : remove common_has_curl() (ggml-org#16351)

`test-arg-parser.cpp` has been updated to work consistently,
regardless of whether CURL or SSL support is available, and
now always points to `ggml.ai`.

The previous timeout test has been removed, but it can be
added back by providing a dedicated URL under `ggml.ai`.
