[OE-core] [PATCH] sqlite3: Fix zlib determinism problem

[Richard Purdie]

sqlite3-native in particular was finding zlib from the host if zlib-devel
was installed. This could lead to races where pseudo-native may or may not
fail to build.

We don't need/use compressed page support with sqlite so disable the dependency
(it doesn't have a configure option so use a autoconf cache variable).
