Subject: [PATCH 50/50] tests: Add t4201 to test partprobe with 1025 devices

This makes sure partprobe is closing the device and doesn't run out of
file descriptors. Uses scsi_debug to create 1025 devices (descriptor
limit is 1024).

Also adds partprobe to the TESTS_ENVIRONMENT PATH, otherwise it will use
the partprobe installed on the system when running the tests.
