games-action/transcend: EAPI6->8, misc cleanups

Slightly annoying to but no longer use Transcend/ in ${S}
given higher level directories are also built and it makes
user patching (or future need to patch) difficult.

Also try to use the more "intended" way to build to drop
large sed/makefile concat.

Drop unused X deps and prevent from attempting to link with them.
