switch git URL of parsoid/integration to git proto

I had some issue with HTTP as a protocol to fetch Zuul references from,
so complete the migration of parsoid and integration jobs to use git://
protocol just like the rest.

Updates jobs:

integration-jjb-config-test
parsoid-parse-tool-check
parsoid-parsertests-run
parsoid-parsertests-run-harder
parsoid-php-parsertests
parsoid-regressions
parsoid-roundtrip-test-check
parsoidsvc-php-parsertests
