[PATCH] test: fix die() in test-lib.sh and test-lib-common.sh

[Tomi Ollila]

Restoring fd was forgotten in die() implemented in test-lib.sh
(so far it did not matter as the only place die was called the
standard fd redirections were not in effect).

In scripts that include test-lib-common.sh but not test-lib.sh
the die() implementation needs to be a bit different due to
fd redirection differences. test-lib-common.sh implements die()
only if it was not implemented already.
