dma-buf: Introduce selftesting framework
In light of recent review slip ups, the absence of a suite of tests for dma-buf became apparent. Given the current plethora of testing frameworks, opt for one already in use by Intel's CI and so allow easy hook up into igt. We introduce a new module that when loaded will execute the list of selftests and their subtest. The names of the selftests are put into the modinfo as parameters so that igt can identify each, and run them independently, principally for ease of error reporting.
