Subject: [PATCH 3/5] tools: selftests: riscv: Add missing include for vector test

From: Christoph Müllner <christoph.muellner@...ll.eu>

GCC raises the following warning:
  warning: 'status' may be used uninitialized
The warning comes from the fact, that the signature of waitpid() is
unknown and therefore the initialization of GCC cannot be guessed.
Let's add the relevant header to address this warning.
