[ptxdist] [PATCH] Add 'libpipeline'

[Juergen Beisert <jbe@pengutronix.de>]

From its README:
libpipeline is a C library for setting up and running pipelines of processes,
without needing to involve shell command-line parsing which is often
error-prone and insecure. This alleviates programmers of the need to
laboriously construct pipelines using lower-level primitives such as fork and
execve.
