File htdig-unsigned-char.patch of Package htdig

From: Dominique Leuenberger <dimstar@opensuse.org>

USe unsigned char in order to ensure we can store values up to (int)255

Fixes build with gcc 6, which failed with:
[  300s] Accents.cc:78:42: error: narrowing conversion of '128' from 'int' to 'char' inside { } [-Wnarrowing]
[  300s]     'o', 'u', 'u', 'u', 'u', 'y', 254, 255};
