Hi,

when the http(-ipv6) server can't be started, the rest of the testsuite
breaks, instead of just skipping those tests that can't be run. the
attached patch fixes that.

Background: currently the testsuite breaks when building an IPv6-enabled
curl on a host that has no (runtime) IPv6 support (*). While running the
testsuite on such host might not make too much sense, it still shouldn't
fail because of the http-ipv6 tests. A next step is to detect such
system in the beginning and don't even try to start the http-ipv6 and
ftp-ipv6 servers. I'll send a separate patch later.

Michal
