While this is correct in checking that the contents are compressed
under --with-zlib, this also removes the coverage where we make sure
that this command is able to complete under --without-zlib without
compressing any of the table data files.  Hence my point from
upthread: this test had better not use compile_option, but change
glob_pattern depending on if the build uses zlib or not.

In order to check this behavior with defaults_custom_format, perhaps
we could just remove the -Z6 from it or add an extra command for its
default behavior?
