Exec dmesg and awk to print everything in the message buffer

following "panic:" or "Fatal trap".  `panicstr' is still printed,
although it is redundant if there is a valid message buffer and
incomplete if it contains `%'s.  I think the awk command belongs
here and not in a script since a standard format with complete
messages is good for bug reports.
