Fix variable initialization when using buffering build with GiST This can cause valgrind to complain, as the flag marking a buffer as a temporary copy was not getting initialized.
While on it, fill in with zeros newly-created buffer pages. This does not matter when loading a block from a temporary file, but it makes the push of an index tuple into a new buffer page safer. This has been introduced by 1d27dcf, so backpatch all the way down to 9.4.
