Bug#667861: libgtk-3-bin: gtk-update-icon-cache diversion bugs

[Adrian Bunk]

Package: libgtk-3-bin
Version: 3.2.3-1
Severity: important

- libgtk-3-bin diverts /usr/sbin/update-icon-caches to
  /usr/sbin/update-icon-caches.gtk2, which is a nop since
  the file is actually /usr/bin/gtk-update-icon-cache
  (note that there are two mistakes in the path+filename)
- when fixing that, please also fix the bigger bug that
  there is no update-icon-cache symlink in libgtk-3-bin
- for the man page there are similar problems
