gnu: k3b: Add inputs for libraries loaded at runtime.

Patch the source to load these from absolute paths. Actual loading is done by
the Qt library, so we cannot use k3b’s runpath.

* gnu/packages/kde-multimedia.scm (k3b)[inputs]: Add libcdio-paranoia and
libdvdcss.
[arguments]<#:phases>[set-absolute-library-paths]: New phase.
