test: port 44 vcs/downloader/version tests using mock infra

Port git, version_guesser, gitlab_driver, github_driver, and git_downloader
tests using the ProcessExecutor/HttpDownloader mocks and IO/Config stubs.
Fix production regex-porting bugs surfaced by the now-reachable paths:
Url::sanitize and Response::find_header_value had non-delimited PCRE patterns;
implement array_search_mixed non-strict branch and a datetime format mapping.
Add HttpDownloader::__new_mock so mocked downloaders skip curl construction.
