Bug#896932: file: detect monitor EDID file format

[Gürkan Myczko]

as talked on irc, the patch could be like this:

# magic for EDID metadata files
0    string    \x00\xff\xff\xff\xff\xff\xff\x00    EDID metadata
I haven't tested it, but put it in your /etc/magic, and run file on your 
data files

Best,
