[PATCH 2/2] perror: avoid spurious test failure on HP-UX

[Eric Blake]

The next-to-last command in this test has non-zero status.  Even
though 'exit 0' is supposed to ignore prior status, HP-UX /bin/sh
favors the prior status if an exit trap is installed.

* tests/test-perror.sh: Use Exit to avoid wrong exit status.
