TestEXIF failing

[Tachi107]

Hi!

When trying to build the project, I encountered a test failure of TestEXIF test.

Build environment:

• bimg 1.1.9
• go 1.24
• libvips 8.16.1
• Debian Testing (forky)

Here's the error:

=== RUN   TestEXIF
    metadata_test.go:268: Unexpected image exif ExifVersion: Exif Version 2.31 != Unknown Exif Version
--- FAIL: TestEXIF (0.01s)

Related to #479

Here's a diff fixing the issue. Of course, this will break the test for old libvips versions.
