Use correct curl-config program

Instead of calling directly curl-config in src/Makefile (which ends up
calling the wrong curl-config: the one in the PATH instead of the one
pointed at by the environment variables at configure time), let's
define a CURL_CONFIG variable that contains the path to the proper
curl-config program, and use it where appropriate.
