ath10k-ct-firmware: add conflicts and better provides

This expands packages to define not only provides but also conflicts.
These packages provides same files so they should specify conflicts.

Second expansion is that *-ct-htt and *-ct-full-htt firmwares can also
provide *-ct variant as that allows explicit dependency on CT variant
with various firmware modifications.
