nixos/postgresql: drop ensurePermissions option

...effectively what was planned already in #266270, but it was too late
because the branches were restricted and didn't allow any breaking
changes anymore.

It also suffers from the same issue that we already had when discussing
this the last time[1] when `ensureDBOwnership` was ultimately introduced
as band-aid fix: newly created users don't get CREATE permission on
the `public` schema anymore (since psql 15), even with `ALL PRIVILEGES`.

If one's use-case is more sophisticated than having a single owner, it's
questionable anyways if this module is the correct tool since
permissions aren't dropped on a change to this option or a removal which
is pretty surprising in the context of NixOS.
