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.
