[PULL 15/18] tests/qtest/ide-test.c: Create disk image for use as a secondary

[Kevin Wolf <kwolf@redhat.com>]

From: Lev Kujawski <lkujaw@member.fsf.org>

Change 'tmp_path' into an array of two members to accommodate another
disk image of size TEST_IMAGE_SIZE.  This facilitates testing ATA
protocol aspects peculiar to secondary devices on the same controller.
