t/t9001-send-email.sh: ensure generated script is executed with $SHELL_PATH

If the shell is not specified using the '#!' notation, then the OS will
use '/bin/sh' to execute the script which may not produce the desired
results.  In particular, /bin/sh on Solaris interprets '^' specially which
has an effect on the sed command that this patch touches.
