parselogs: Whitelist GPT warnings as the device is fully functional

The warning occurs when the GPT image is not the same size than the
media into which it's being flashed, causing the backup GPT table
not being at the end of the disk. However, this is expected as the
image is created before having the information about the destination
media. The error is harmless, so it will be whitelisted.

Fixes [YOCTO 10481].
