Current implementation does not handle possible exceptions coming from child
processes, the latter responsible for creating packages. With the aim to have
more
control, use pipes to communicate exceptions and stop package creation in case
of failure.
Helps to debug [YOCTO #12012].

Other than the name is IPKWritePkgProcess the same as DebianWritePkgProcess?
If so, could we put a single WritePkgProcess class somewhere it can be
shared in lib/oe ?
