Reuse all-zero pages in GIN.

In GIN, an all-zeros page would be leaked forever, and never reused. Justadd them to the FSM in vacuum, and they will be reinitialized when grabbedfrom the FSM. On master and 9.5, attempting to access the page's opaquestruct also caused an assertion failure, although that was otherwiseharmless.Reported by Jeff Janes. Backpatch to all supported versions.
