midori: update from 0.4.4 to 0.5.6 (close #1411)
tmpwatch: Add platforms to meta (unix).

According to web pages of tmpwatch it seems that it can be build on
unixes (Mac OS X, solaris). Not much information is here though.
Add targetcli-fb as well as necessary dependencies
Update node packages to npm2nix-5.4.2 to fix tarball

Thanks @vcunat for pointing it out
