test_connection_keepalive(TestCurbCurlMulti) skipped with Curl 8+

[voxik]

I know the Curl 8+ is out of support matrix. Nevertheless, Curl 8.4.0 is the version available in Fedora and everything seems to be fine except that test_connection_keepalive(TestCurbCurlMulti) is skipped. This seems to be due to this condition:

curb/tests/tc_curl_multi.rb

Line 16 in 13144ec

omit("Skip, libcurl too old (< 7.22.0)") if Curl::CURL_VERSION.split('.')[1].to_i <= 22

Which does not account for major version.

The commit 06e81e6 introducing the condition above remove use Google, while the test case keeps referring to Google:

curb/tests/tc_curl_multi.rb

Line 25 in 13144ec

# additionally, if ss allows this to pass on linux without requesting google i think this is a good trade off... leaving some of the thoughts below

curb/tests/tc_curl_multi.rb

Lines 78 to 79 in 13144ec

	assert (after_open - before_open) < 3, "with max connections set to 1 at this point the connection to google should still be open"
	assert (after_open - before_open) > 0, "with max connections set to 1 at this point the connection to google should still be open"
