beamPackages: Deduplicate default package set

Browse source 
Previously there were two package sets for the default Erlang version,
beam.packages.erlang and beam.packages.erlangR24, which didn't share
their evaluation.

This commit fixes this by pointing the former to the latter. It also
introduces a `beam.defaultVersion` attribute which can be used to get or
set the default version to something other than `erlangR24`.
