x86/dumpstack: use %pSb/%pBb for backtrace printing
Let's use the new printk formats to print the stacktrace entries when
printing a backtrace to the kernel logs. This will include any module's
build ID[1] in it so that offline/crash debugging can easily locate the
debuginfo for a module via something like debuginfod[2].
