Subject: [PATCH] Switch git instaweb default to apache

On Fedora-derived systems, the apache httpd package installs modules
under /usr/lib{,64}/httpd/modules, depending on whether the system is
32- or 64-bit.  A symlink from /etc/httpd/modules is created which
points to the proper module path.  Use it to support apache on Fedora,
CentOS, and Red Hat systems.

References upstream commit: 1976311aa285549599e5a451d7ad72b55a2b60e2
