[PATCH] t/helper: ignore everything but sources

[Stefan Beller <sbeller@google.com>]

Compiled test helpers in t/helper are out of sync with the .gitignore
files quite frequently. This can happen when new test helpers are added,
but the explicit .gitignore file is not updated in the same commit, or
when you forget to 'make clean' before checking out a different version
of git, as the different version may have a different explicit list of
test helpers to ignore.

Fix this by having an overly broad ignore pattern in that directory:
Anything, except C and shell source, will be ignored.

Yes, there is also one lonely shell script in there, which also needs
exclusion.

 I guess we want to test this overly broad pattern in a sub directory,
 as I could imagine that at the top level directory we'd have more cases
 to think through (I used to put untracked files into the top level dir,
 but I do not do it anymore).
 
Thanks,
Stefan
