tests/*.sh : Switch back to /bin/sh.

Jan Stary reported that on OpenBSD bash isn't located in /bin/
which means that the test fail. He also noted that there didn't
seem to be anything bash specific in the tests.

This patch takes some suggestions from Jan, plus a few fixes tested
on Debian using the bin/sh provided by bash and dash.

Suggested-by: Jan Stary <hans@stare.cz>
