[PATCH] Skip t5540-http-push test when USE_CURL_MULTI is undefined

When USE_CURL_MULTI is undefined, git http-push doesn't work, so it's
useless to test it.
---

 I wasted too much time wondering why the 3rd and 4th tests were failing
 before realizing I was building against an ancient libcurl, thus having
 a non working git http-push. This would avoid other people to do the same.
