<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix FIT image detection for larger image files. (MR: reproducible-builds/diffoscope!75)
Use manual magic comparison for FIT images (device tree blob) to work
around a bug in libmagic that results in device tree blob files not
correctly being identified when the structure section is larger than 1MB.
libmagic bug report: https://bugs.astron.com/view.php?id=232
