[File] [PATCH] Add ESL SHA256 Test

[Benedikt Radtke]

Hey,

I prowled through file's code base because Ubuntu24's file fails to identify EFI Signature List files. I realized too late that noble ships file 5.45, and incorrectly briefly assumed that the guids in the Magdir were defined in the wrong endianess. I added a test file assuming that it would fail, but 5.46+ correctly identifies ESLs.

The passing test is attached, since I figured you might want to merge it. It might save someone from going into the same rabbit hole, although more recent versions of Ubuntu have a more recent version of file.

Kind regards,
Benni
