daemon: check: Keep the differing output if -K is given.
This makes it easier to investigate the non-determinism, e.g. $ nix-build pkgs/stdenv/linux -A stage1.pkgs.zlib --check -K error: derivation ‘/nix/store/l54i8wlw22656i4pk05c52ngv9rpl39q-zlib-1.2.8.drv’ may not be deterministic: output ‘/nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8’ differs from ‘/nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8-check’ $ diffoscope /nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8 /nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8-check ... ├── lib/libz.a │ ├── metadata │ │ @@ -1,15 +1,15 @@ │ │ -rw-r--r-- 30001/30000 3096 Jan 12 15:20 2016 adler32.o ... │ │ +rw-r--r-- 30001/30000 3096 Jan 12 15:28 2016 adler32.o ...
