header generation changed

[David Faure]

I ported all the frameworks to Alex Merry's new ecm_generate_headers syntax.

Just a heads up: you will have to clean up your build dirs to avoid errors 
like:

  install FILES given directory
  "/d/kde/build/5/frameworks/kwallet/src/api/KWallet/KWallet" to install.

This is because the builddir had a directory "KWallet", and now we want to 
generate a file "KWallet" instead.
