Runs having only KCSAN reports will normally print a summary line
containing only a "Bugs:" entry. However, these bugs might or might
not be KCSAN reports. This commit therefore flags runs in which all the
"Bugs:" entries are KCSAN reports.

Commit 757055ae8d ("init/console: Use ttynull as a fallback when
there is no console") results in the string "Warning: Failed to add
ttynull console. No stdin, stdout, and stderr for the init process!"
appearing on the console, which the rcutorture scripting interprets as
a warning, which causes every rcutorture run to be flagged. However,
the rcutorture init process never attempts to do any I/O, and thus does
not care that it has no stdin, stdout, or stderr.
This commit therefore causes the rcutorture scripting to ignore this
message.

The "NOHZ tick-stop error: Non-RCU local softirq work is pending"
warning happens frequently and appears to be irrelevant to the various
torture tests. This commit therefore filters it out.
If there proves to be a need to pay attention to it a later commit will
add an "advice" category to allow the user to immediately see that
although something happened, it was not an indictment of the system
being tortured.

This commit pulls the simple pattern-based error detection from the
console log into a new console-badness.sh file. This will enable future
commits to end a run on the first error.
