Currently, the symbol ".rodata" may not be found in some vmlinux, and
the strings command will still be used to get the linux banner string,
but this gets two strings as below:
# strings /usr/lib/debug/usr/lib/modules/6.5.0-0.rc2.17.fc39.x86_64/vmlinux
|grep "Linux version"
Linux version 6.5.0-0.rc2.17.fc39.x86_64
(mockbuild@23a79bad375e4c2c8c60f2d40df7df49) (gcc (GCC) 13.1.1 20230614 (Red
Hat 13.1.1-4), GNU ld version 2.40-9.fc39) # SMP PREEMPT_DYNAMIC
Linux version 6.5.0-0.rc2.17.fc39.x86_64

In the verify_namelist(), the while-loop will only determine if the
above first string(linux banner) matches and break the loop. But
actually the above second string is correct one. Eventually, crash
startup with the following warning:
# ./crash -s
/usr/lib/debug/usr/lib/modules/6.5.0-0.rc2.17.fc39.x86_64/vmlinux
/var/crash/127.0.0.1-2023-07-20-20\:50\:50/vmcore
WARNING: kernel version inconsistency between vmlinux and dumpfile
# ./crash -s
WARNING: kernel version inconsistency between vmlinux and live memory
Let's always try to match the correct one, otherwise still prints a
warning as before.
