util-macros: remove this package from IPFire

- util-macros was originally installed as a build requirement for pciaccess which is
   a dependency of libvirt
- Along the way of updates of pciaccess the build requirement for util-macros is no
   longer needed. pciaccess built without problems with util-macros removed.
