For the log entry that has multiple lines, "makedumpfile --dump-dmesg"
would indent the remaining lines while vmcore-dmesg doesn't. For
example, vmcore-dmesg.txt and vmcore-dmesg.txt.2 are the outputs of
vmcore-dmesg and "makedumpfile --dump-dmesg" respectively,
```
diff -u vmcore-dmesg.txt vmcore-dmesg.txt.2

Quite often, all three tests could fail because of the above difference. So
let's ignore all the spaces. This patch could fix bz1952299 [1].
