This is work torward the ability to run the testbench in parallel. Some small issues in tests have also been detected, which were not previously seen. They have been fixed. We did not do separate commits for this as it would clutter the commit log with not really relevant info. Also move some cleanup to "make clean" target To support parallel testbench runs, we need to have dynamic work files. So deleting work files on each test does not work, especially as we can no longer assume they are "left-overs" from a failed test - they may actually (and quite likely) belong to tests that run in parallel. So the proper solution is to do via "make clean". closes https://github.com/rsyslog/rsyslog/pull/2916

# This test checks that omprog restarts the external program when it

# terminates prematurely, and that it does so without leaking file
|
|
# descriptors. Two cases are checked: termination of the program when
|
|
# omprog is going to write to the pipe (to send a message to the
|
|
# program), and when omprog is going to read from the pipe (when it
|
|
# is expecting the program to confirm the last message).
