kernel/panic: add verbose logging of kernel taints in backtraces
With nearly 20 taint flags and respective characters, it's getting a bit
difficult to remember what each taint flag character means. Add verbose
logging of the set taints in the format:
Tainted: [P]=PROPRIETARY_MODULE, [W]=WARN
in dump_stack_print_info() when there are taints.
Note that the "negative flag" G is not included.
