[LTP] [PATCH 2/2] Add wanted output to shell lib test case

[Christian Lanig <clanig@suse.com>]

---
Please do not merge!
I would like to get some feedback for this one and the previous patch. It is
based on Petr Vorel's [RFC,v3,2/2] lib: Add tests from May 22nd 2018 with the
message ID 20180522193430.20117-2-pvorel@suse.cz.
These two patches transfer Petr's test cases in a separate folder and a shell
script loops over all files as suggested in the replies to the initial message.
The output is verified against a comment section in the test case file itself.
This section is started with the line "# output:" and it is expected that it
goes to the end of the document without interception.
I have run the script with various Shell implementations to make sure it's
portable.

Limitations:
The script is currently unable to test e.g. whether TFAIL is displayed with red
color.
So far I have only added the correct output line in a single test case file so
just one test is currently passing.
Before proceeding I would like to know whether this is a good way to go.
