Code quality fixes from review

toolsrv:
- Remove dead 'var _ = os.Args' in sandbox/native_linux.go
- Fix stale comment in server.go (said 'spec.go')
- Fix misleading test comment in proc_test.go
- Add outputLimit constant in exec.go (was magic number)
- Handle error from registry.New() in main.go
- Change startup log from Warn to Info

olliesrv:
- Remove duplicate normalizeWorkflow() call in tool_match.go
- Consolidate duplicate nil checks in runtime.go
- Remove reimplemented stdlib functions in toolclient/toolsrv.go
- Simplify cacheSummary() - remove unused variable capture
