selftests: ublk: move test temp files into a sub directory

Browse Source 
Create and use a temporary directory for the files created during
test runs. If TMPDIR environment variable is set use it as a base
for the temporary directory path.
TMPDIR=/mnt/scratch make run_tests
and
TMPDIR=/mnt/scratch ./test_generic_01.sh
will place test directory under /mnt/scratch
