[PATCH] t/lib-httpd: pass through GIT_CONFIG_NOSYSTEM env

We set GIT_CONFIG_NOSYSTEM in our test scripts so that we do not accidentally read /etc/gitconfig and have it influence the outcome of the tests. But when running smart-http tests, Apache will clean the environment, including this variable, and the "server" side of our http operations will read it.

You can see this breakage by doing something like:

  make
  ./git config --system http.getanyfile false
  make test

which will cause t5561 to fail when it tests the fallback-to-dumb operation.

We can fix this by instructing Apache to pass through the variable. Unlike with other variables (e.g., 89c57ab3's GIT_TRACE), we don't need to set a dummy value to prevent warnings from Apache. test-lib.sh already makes sure that GIT_CONFIG_NOSYSTEM is set and exported.

Obviously trivial enough for "maint", but not at all urgent; it has
been this way for ages. I only noticed because I happened to recently
munge my system config to replicate a particular server config which
disables http.getanyfile.
