[PATCH] Ensure SHELL_PATH is the hash bang for test suite askpass helper script.

[Ben Walton <bdwalton@gmail.com>]

The askpass script that is created for use by the test suite should
use SHELL_PATH for its hash bang instead of /bin/sh. Commit 5a4352024
introduced the use of idioms not supported in some legacy /bin/sh
implementations.

Use write_script to ensure this happens automatically. This lets us
remove the chmod step as well, since write_script handles that.
