Fix data loss on crash after sorted GiST index build.
If a checkpoint happens during sorted GiST index build, and the system
crashes after the checkpoint and after the index build has finished,
the data written to the index before the checkpoint started could be
lost. The checkpoint won't fsync it, and it won't be replayed at crash
recovery either. Fix by calling smgrimmedsync() after the index build,
just like in B-tree index build.
Backpatch to v14 where the sorted GiST index build was introduced.
