Add support for a GITANO_PLUGIN_PATH in install-lua-bin

The binary installer `install-lua-bin` needs to update all of the files ending
in `.in` to be ready for installation.  This patch ensures that we support a
tag for loading plugins which the various `.in` files can then use to ensure
they load plugins at an appropriate point.
