neqjoinsel must now pass through collation to eqjoinsel. Since commit 044c99bc5, eqjoinsel passes the passed-in collation to any operators it invokes. However, neqjoinsel failed to pass on whatever collation it got, so that if we invoked a collation-dependent operator via that code path, we'd get "could not determine which collation to use for string comparison" or the like.
Per report from Justin Pryzby. Back-patch to v12, like the previous commit.
