tests: fix grep expressions for devices

ts_is_mounted "/dev/loop1" returned true if /dev/loop17 was
mounted. A very annoying source of sporadic failures since
many years. This issue became more visible since running the
checks in parallel, which increases the probability to get
bigger loop device numbers.
