HaikuDepot : Generate Sources -Fix Build

In recent changes to HD's build files to generate
some sources at build-time there was a problem
with builds that were configured to run with some
element of concurrency.  In this change, the steps
that should be in sequence are done with shell
commands to avoid race conditions.
