* Fix eval-release.nix by testing whether all attributes of a

derivation evaluate inside the tryEval.  This catches cases such as
  aufs2-util, which fails due to an assertion in its dependency aufs2.
* Explicitly blacklist "xbursttools" because it gives some
  evaluation error in cross-OpenSSL.  No idea why, probably due to
  some pass-through attribute.
