t/lib-httpd: handle running under --valgrind

Running the http tests with valgrind does not work for two reasons: 1. Apache complains about following the symbolic link from git-http-backend to valgrind.sh. 2. Apache does not pass through the GIT_VALGRIND variable to the backend CGI. This patch fixes both problems. Unfortunately, there is a slight hack we need to handle passing environment variables through Apache. If we just tell it: PassEnv GIT_VALGRIND then Apache will complain when GIT_VALGRIND is not set. If we try: SetEnv GIT_VALGRIND ${GIT_VALGRIND} then when GIT_VALGRIND is not set, it will pass through the literal "${GIT_VALGRIND}". Instead, we now unconditionally pass through GIT_VALGRIND from lib-httpd.sh into apache, even if it is empty.
