Remove update-ghdl-libraries and associated configuration for now
As the way libraries are organized has changed between ghdl 0.35 and the git snapshot now packaged, update-ghdl-libraries won't work without changes. In fact, the changes would make it easier to organize but at this point let's get ghdl back into the archive without this feature and design it back in later. This also changes library handling in the way that the standard libraries are again prebuilt and installed with the package.
