[PATCH] fdtdump: fix output of bytestring properties

[Prusov Igor Vladimirovich <Igor.V.Prusov-wnI+JWxWOPs@public.gmane.org>]

Currently, when fdtdump prints bytestring property, it prints ffffff 
in front of bytes with first bit equal to 1 (0x80 - 0xff)

For example:
property = [80];
will become
property = [ffffff80];
This patch fixes it.
