[PATCH v2 1/3] tests: Prepare --textconv tests for correctly-failing conversion program

<6b2704af93283143d7756a1fa0fd52411e689292.1285013802.git.kirr@landau.phys.spbu.ru>

(Description by Matthieu Moy)

The textconv filter is sometimes incorrectly ran on a temporary file whose content is the target of a symbolic link, instead of actual file content. Prepare to test this by marking the content of the file to convert with "bin:", and let the helper die if "bin:" is not found in the file content.
