package/gerbera: needs dynamic library

Disable gerbera with static builds as it raises build failures since
bump to version 1.8.0 in commit 8974596836945eada8e162844fb87f88adec9100
and upstream does not seem to care or test static builds:
https://github.com/gerbera/gerbera/issues/1221

Fixes:
 - http://autobuild.buildroot.org/results/9c59ef912d09bb3c0647b98aa8e9eca7fccbe08f
