Update truffleruby-gftc-dev native build to use newer repo

The new automated graal-languages-ea-builds repo has native builds
that correspond to the new jvm builds available in the main
truffleruby+graalvm-dev definition.

However the main truffleruby-dev definition for native builds uses the
truffleruby-dev-builder repo which is closer to master but uses the CE.
