This diff introduces biber v2.11 that is compatible with texlive-20180414 that is currently promoted in reviews as well. For reference see Bug 211997 and Differential D16623.
The biber doc includes a compatibility matrix that indicates that v2.11 is not compatible with the currently texlive port. v2.12 is already available but not compatible with texlive in Differential D16623, so this version was specifically chosen.
I intentionally removed the dependency to texlive-texmf due to possible conflicts between texlive-texmf and texlive-texmf-* in reviews.
