Subject: Bug #244946 - Use different syntax to pipe find output into while
 loops inside python_mod_cleanup(), as a workaround for a bug in <bash-3.2
 which causes incorrect saving of the environment when < <(find ...) syntax is
 used. The bug causes bash to die when attempting to source the resulting
 environment file. A similar issue has affected eutils.eclass in the past,
 triggering bug #215340.

Also fix inverted argument validation logic inside python_mod_exists(), broken
since version 1.47. Thanks to zlin for reporting.
