disarchive-manifest: Add one manifest entry per tarball.

Browse source 
This works around a situation where ‘cuirass remote-worker’ now builds
with max-jobs = 1 (Cuirass commit
980ef610989895be5ac2ba7f9d1901e5c7f22934).  The effect is that all
.dis.drv would be performed sequentially, on a single machine (‘cuirass
remote-server’ is unable to distribute those derivations to several
machines because it only “sees” the ‘disarchive-collection’ derivation).
This would take a lot of time and force a rebuild of all of *.dis.drv
every time because their build results would not be retrieved by the
‘remote-server’ process.

* etc/disarchive-manifest.scm (disarchive-collection): Remove.
<top level>: Define ‘disarchives’.  Append it to the entries of the
manifest.
