🐛 Fix three entrypoint bugs 🐛

- CONTAINER_NAME was hardcoded to "alpine" instead of "go"; the startup
message said "alpine" for the same reason
- HEALTH_ENABLED was hard-assigned to "yes" after env files were sourced,
silently overriding the HEALTH_ENABLED="no" set in env/go.sh; changed
to ${HEALTH_ENABLED:-yes} so the env file value is respected
- go-workflow used retval (lowercase) to capture the go vet exit code but
then read retVal (uppercase) in the accumulator; the vet failure was
silently dropped and the gofmt exit code was summed twice instead
- rootfs/usr/local/bin/entrypoint.sh: fix CONTAINER_NAME default, startup
message label, and HEALTH_ENABLED hard-override
- rootfs/usr/local/bin/go-workflow: fix retval/retVal case mismatch so
go vet exit code is correctly propagated
