test: explicitly use zlib compression in tests/test-repo-compengines.t

We need the implicit value to be explicit until we can change the default in
some case.

 A new repository uses zlib storage, which doesn't need a requirement

 Unknown compression engine to format.compression aborts
 
   $ hg --config format.revlog-compression=unknown init unknown
   abort: compression engines "unknown" defined by format.revlog-compression not available
   (run "hg debuginstall" to list available compression engines)
   [255]
 
 unknown compression engine in a list with known one works fine
 
   $ hg --config format.revlog-compression=zlib,unknown init zlib-before-unknow
   $ hg --config format.revlog-compression=unknown,zlib init unknown-before-zlib
 
 A requirement specifying an unknown compression engine results in bail
 
   $ hg init unknownrequirement
   $ cd unknownrequirement
   $ echo exp-compression-unknown >> .hg/requires
   $ hg log
   abort: repository requires features unknown to this Mercurial: exp-compression-unknown
   (see https://mercurial-scm.org/wiki/MissingRequirement for more information)

 Specifying a new format.compression on an existing repo won't introduce data
 with that engine or a requirement
