Subject: [PATCH 2/2] tags: Don't allow image tags with G_MAXUINT32 length

This will cause an integer overflow a little bit further down because we
allocate a bit more memory to allow for a NUL-terminator.

The caller should've avoided passing that much data in already as it's
not going to be a valid image and there's likely not even that much data
available.
