Michael Paquier 4fea343493 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.
