tools/fitimage: make sure dumpimage still works when "@" are detected

Browse source 
fit_verify_header fails if it detects unit addresses "@". However, this
will break tools like dumpimage on fit images which worked with previous
versions of the tool (e.g. 2020.04 vs 2021.07). As an example the output
of:
dumpimage -l <fit image>
is:

But with newer version it shows:
dumpimage -l <fit image>
GP Header: Size d00dfeed LoadAddr 62f0a4

This commit will output a warning that unit addresses were detected but
will not fail:
dumpimage -l <fit image>
Image contains unit addresses @, this will break signing
