rtemstoolkit: Fix shlex.split to use posix mode and add unit test for pipe operation

Turns out subprocess.Popen operates on posix mode. Also, there is an
issue with previous implementation of pipe command that is fixed by
Chris. Now, it can also accepts command in form of a string. The unit
test for that is added via this patch.
