libstdc++: Fix ip::tcp::resolver test failure on Solaris 

Solaris 11 does not have "http" in /etc/services, which causes this test
to fail. Try some other services until we find one that works.

Signed-off-by: Jonathan Wakely <jwakely@redhat.com>

libstdc++-v3/ChangeLog:

	* testsuite/experimental/net/internet/resolver/ops/lookup.cc:
	Try other service if "http" fails.
