check_curl: fix relative redirects on non-standard port

Having a webserver respond with a relative redirect as for ex. in `Location: /path/to.html`
check_curl would use the wrong standard http/https port instead
of crafting the absolute url using the given scheme/hostname and port.

Adding a new test case for this for check_http and check_curl. check_http did
it correct already, so no fix necessary there.

before:

    %>./check_curl -H 127.0.0.1 -p 50493 -f follow -u /redirect_rel -s redirected -vvv
    **** HEADER ****
    HTTP/1.1 302 Found
    ...
    Location: /redirect2

    ...
    * Seen redirect location /redirect2
    ** scheme: (null)
    ** host: (null)
    ** port: (null)
    ** path: /redirect2
    Redirection to http://127.0.0.1:80/redirect2

fixed:

    %>./check_curl -H 127.0.0.1 -p 50493 -f follow -u /redirect_rel -s redirected -vvv
    **** HEADER ****
    HTTP/1.1 302 Found
    ...
    Location: /redirect2

    ...
    * Seen redirect location /redirect2
    ** scheme: (null)
    ** host: (null)
    ** port: (null)
    ** path: /redirect2
    Redirection to http://127.0.0.1:50493/redirect2
