package/dht: fix cmake4 compatibility

The only dependee of dht, transmission, forked dht due to upstream
rejection of cmake support:
https://github.com/jech/dht/pull/50
https://github.com/jech/dht/pull/19

A fix was added to this fork for building with cmake 4.x:
https://github.com/transmission/dht/commits/post-0.27-transmission/

Instead of adding yet another patch to buildroot we switch to the repo
maintained by transmission.

Fixes:
https://autobuild.buildroot.org/results/30339a4fdb9c0b608ca3c5ae0692596b21b2fc3f/
