  [Impact]

   * Cannot input languages which need IM(ibus, fcitx) in Qt5 apps, e.g.
  webapp-container, webbrowser-app, friends-app, etc.

  [Test Case]
   1. prepare ibus or fcitx environment with CJK(Chinese, Japanese, Korean) language, for example.
   2. install and launch webbrowser-app
   3. confirm that you cannot enable IM inside webbrowser-app
   4. update im-config packages to -proposed one
   5. logout from desktop session and re-login
   6. confirm that now you can enable IM and input CJK language with ibus or fcitx.

  [Regression Potential]

   * This patch sets QT_IM_MODULE which might affect Qt4 app behaviour,
  both Qt5 and Qt4 app tests are preferred to make sure there is no
  regression for both sides. I used webbrowser-app(Qt5) and skype(Qt4)
  before attaching the patch.

  WORKAROUND:
  launch webapp-container with QT_IM_MODULE variable like the line below.

  $ env QT_IM_MODULE=ibus webapp-container --app-id=Gmailmailgooglecom
  --webapp=XXXXXX --enable-back-forward --store-session-cookies

  webapp-container looks like QT5 application, im-config needs to care
  about QT_IM_MODULE in addition to other *_IM_MODULE variables?
