[PATCH v3 rcu 8/8] torture: Make torture.sh create a properly formatted log file

[Paul E. McKenney]

Currently, if the torture.sh allmodconfig step fails, this is counted as
an error (as it should be), but there is also an extraneous complaint
about a missing log file.  This commit therefore adds that log file,
which is hoped to reduce confused reactions to the error report.
