[PATCH] cgit.mk: fix dependency handling

[John Keeping]

Git calculates the dependency files to be included using a simply
expanded Makefile variable, so it does not include the CGit objects that
are added after that Makefile has been processed.

We therefore need to include the dependency files ourselves in order to
get the dependency calculations right.  Do this.

I missed this when changing this to use Git's Makefile - it all worked
nicely until I started jumping between branches :-(
