trinity-base-2.eclass: Begin to make set-trinityver/need-trinity obsolete

This remains conditional on BUILD_TYPE=live for now as this is where we can
experiment with things.

Set only relevant bits we need from these functions directly in here:
- TRINITY_VER
- TDEDIR
- TDEDIRS
- Dependency on trinity-base/tdelibs

In a follow-up commit, set-trinityver() and need-trinity() will become no-ops
for BUILD_TYPE=live.
