Make bootstrap process wrapper honor '-' as stdout/stderr

For the process wrapper the value '-' has a special meaning
as file name to which stdout/stderr are to be redirected: do
not redirect. However, the simple shell script that serves
as process wrapper during the bootstrap phase was not aware
of this special meaning, resulting in loss of useful process
output, which is especially annoying during bootstrap. Fix this.
