daemon: check: Fix assertion failure when some outputs are missing.
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.
