Temporarily disable binary swap test, until the next beta is tagged.

The pg_control change to bring in heap checksum from upstream is breaking
binary compatibility.  As soon as that is merged, binary swap test will start
failing.  Disable it now.  It will be re-enabled once a new beta tag is
generated.  Thereafter, binary swap test will verify binary compatibility
between the new beta tag and HEAD.
