tests: ignore http tests that are known wontfix failures on python 2.4 As mentioned on http://bz.selenic.com/show_bug.cgi?id=2739#c17 , b3083042bdda left test-http.t failing on Python < 2.4.3. That has not been noticed because most 2.4 testing has been done with a patched 2.4.2. This makes sure that the tests only are run for Python >= 2.4.3. That makes it possible to verify that everything else works with Python 2.4.

import-checker: fix names of dynamically loaded modules The import checker found standard library modules such as lib-dynload/zlibmodule.so but saw that as a 'zlibmodule' module, not as the 'zlib' module. Debian ships Python with most modules built-in and this incorrect handling of dynamic modules did thus not cause problems on that platform. Fedora ships Python with as many modules as possible loaded dynamically. That made the import checker tests fail with incorrect classification of the following modules: array fcntl grp itertools time zlib. This change makes test-module-imports.t pass on Fedora.

tests: for consistent output flush between writing sterr and stdout Because stdout and stderr are buffered, the order of the output is other way around on some systems.
