[PATCH] gitweb: Fix export check in git_get_projects_list

["Devin Doucette" <devin@doucette.cc>]

When $filter was empty, the path passed to check_export_ok would
contain an extra '/', which some implementations of export_auth_hook
are sensitive to.

It makes more sense to fix this here than to handle the special case
in each implementation of export_auth_hook.
