[OE-core] [PATCH 1/1] xcursor-transparent-theme: install index.theme explicitly

[wenzong.fan at windriver.com]

The xcursor-transparent-theme doesn't install index.theme by default,
this might cause below command fails on target:

    $ gtk-update-icon-cache -q /usr/share/icons/xcursor-transparent
    Error: "gtk-update-icon-cache: No theme index file"

Just install index.theme explicitly to remove those error, its content
is from xcursor-transparent-theme's README file.

[YOCTO #4234]
