--check: Fix assertion failure when some outputs are missing

Browse source 
E.g.

  $ nix-build pkgs/stdenv/linux/ -A stage1.pkgs.perl --check
  nix-store: src/libstore/build.cc:1323: void nix::DerivationGoal::tryToBuild(): Assertion `buildMode != bmCheck || validPaths.size() == drv->outputs.size()' failed.

when perl.out exists but perl.man doesn't. The fix is to only check
the outputs that exist. Note that "nix-build -A stage1.pkgs.all
--check" will still give a (proper) error in this case.
