Another solution is the Epoch: tag. It is used in version comparisons
even before the version. So setting the epoch to a number higher of the
Fedora package (No Epoch is treated as 0) will make all Fedora updates
"older" that your modified package. To be on the save side you could
increase the Epoch by more than one.

As already pointed out there are better solution to your problem. So
just for completeness:

You can do things in the rpmdb only using --justdb. This can be used
make rpm belief a package is installed when it is not (on disk) or that
a package is removed while still being on the disk.

But this is something you generally should not do as rpm will happily
stomp on your files on disk if it installs or updates a package sharing
some paths. Also you give up all compatibility/dependency checking.
