Accepting request 494566 from home:alarrosa:branches:multimedia:libs

DimStar suggested this solution in order to build with all versions of gperf

- Add BuildRequires: zypper and use it to check for gperf version so
  the package builds with all versions of gperf (boo#1027205)

  of the hash/lookup function (boo#1027205)
