check_curl: fix checking large bodys (#1823)
check_curl fails on large pages: HTTP CRITICAL - Invalid HTTP response received from host on port 5080: cURL returned 23 - Failure writing output to destination for example trying to run check_curl on the test from #1822 I guess the idea is to double the buffer size each time it is to small. But the code exponentially grows the buffer size which works well 2-3 times, but then fails.
