Remove recordExtensionInitPriv[Worker]'s ownerId argument.

Browse Source 
In the wake of the previous commit, we're not doing anything
with that argument.  Hence, revert the portions of 534287403
that added that argument and taught the callers to pass it.
Passing the ownerId requires additional syscache lookups in
some code paths, which'd be fine if we were doing anything
useful with the info, but it seems inadvisable if we're not.

Committed separately since there's some thought that we might
want to un-revert this in future, in case it's decided that
storing the original owner ID explicitly in pg_init_privs
is worth doing.
