The build/tests/functional subdirectories are consuming huge amounts
of disk space.
Split the location for scratch files into a 'scratch' sub-directory,
separate from log files, and delete it upon completion of each test.
The new env variable QEMU_TEST_KEEP_SCRATCH can be set to preserve
this scratch dir for debugging access if required.

+the tests. If needing to debug a failed test, it is possible to keep these
+files around on disk by setting ```QEMU_TEST_KEEP_SCRATCH=1``` as an env
