Adding a "touch" in .postinst would set the timestamp to the current date and time which should trigger a rebuild of the cache.
The only issues with that is that:
 1) We are (kind of) modifying a file post-install (although the checksum will remain the same so won't really be considered as a change)
 2) We'd need to patch every wallpapers package to include that fix
