Merge lp:~faure/libdbusmenu-qt/fix_qt5_build into lp:libdbusmenu-qt

[David Faure]

Qt5 build: Port to ECM 0.0.4, and use GNUInstallDirs to autodetect "lib64".

[Albert Astals Cid (aacid)]

I think the ECM dependency is a bit weird given that there hasn't been a release but the dependency is not new, so hardly anything I can push agaist.

Besides that It makes sense.
