[PULL,12/56] qemu-iotests: allow valgrind to read/delete the generated log file

From: Emanuele Giuseppe Esposito <[e-mail]>

When using -valgrind on the script tests, it generates a log file
in $TEST_DIR that is either read (if valgrind finds problems) or
otherwise deleted. Provide the same exact behavior when using
-valgrind on the python tests.
