During the code review for a test to exercises AIO/DIO into unwritten space, a number of changes were requested that were also applicable to generic/299 and generic/300 (from which the aforementioned test was patterned). For example, the use of run_check, which is deprecated, was dropped. In addition, we now rely on the test runner to unmount the scratch file system. Also fix a nit I found in generic/095, which resulted in debugging information in the $seqres.full to get lost when "fio ... --output=$seqres.full" is run.
