v0.04.1: Small temporary bandaid fix

Fifth release. Here are the changes:

• Added bandaid that should make pl-init more stable
  • It now forks before executing plSrvInitHalt, as that call can result in a pl-rt panic, which would cause a kernel panic if it were to happen on PID 1

Developer note: i plan on making pl-srv less panicky in v0.05. i just needed to get a bandaid fix out so that portalinux 0.11-rc1 can be released
