mod_vcard_legacy: Include avatar data even if metadata can't be loaded
Normally both nodes should have the same configuration and matching
items, but we can't depend on it without having some code that enforces
it, which does not exist at the time of this commit.
Including the avatar itself should be prioritised. The image format can
be derived from magic bytes.
