Icon theme package dependencies

[Yousuf 'Jay' Philips <ypharis@gmail.com>]

Hello LibreOffice package maintainers,

I volunteer with the libreoffice design team and since 5.0 the icon 
theme packages have changed in their behaviours, so it is important to 
set their mandatory dependencies on other icon theme packages.

* All icon themes packages are dependent on galaxy icon theme package.
* Sifr icon theme package is dependent on breeze icon theme package.

If anyone has contacts with the opensuse libreoffice maintainers, please 
do pass this information to them.
