Revert "changed icons installation path"

This reverts commit 8b8aa87.

Never ever have applications install own actions/status/etc icons
(i.e. anything different than the application own icon, and icons of
needed mimetypes) in the global icon theme, especially if hicolor.
Doing so:
- pollutes the global hicolor theme for *all* the installed application
- increases the risk for actual file conflicts (e.g. two applications
  trying to install the same action icon)
- allow the silent abuse of (private) icons installed with an
  application by other applications

For this reasons, own action icons of krusader should go better in the
private datadir of krusader, as hicolor; versions of those icons
provided by icon themes will override them anyway (and if they do not,
the Qt5 icon loading system is broken).
