test: port 59 autoload/vcs/installer/util/command tests; fix output capture

Port autoload_generator (24), bitbucket (14), suggested_packages (11),
git_driver (6), archive_manager (3), and a bump command test. Fix the
ApplicationTester output-capture root cause (php://memory streams must be
readable regardless of fopen mode). Implement posix_getuid/geteuid, the PCRE
'A' anchored modifier, php_strip_whitespace, stream_get_wrappers, is_callable
scalars; fix preg_quote angle-bracket escaping and class-map parser regexes.
