frank-large: serve script feeds the launcher its runtime root from the SDK venv

The CIRU launcher gates on hip/lib/libamdhip64.so + rocr/lib/libhsa-runtime64.so
under its runtime root and exits 2 without them; the build links the private
venv through its RUNPATH, so point those entries at the venv's unversioned
devel symlinks (idempotent ln -sfn). Without this the unit crash-looped for
the full 2400s health gate on first deploy.
