lib/oe/patch: handle non-UTF8 encoding when reading patches

Browse Source 
When extracting patches from a git repository with PATCHTOOL = "git" we
cannot assume that all patches will be UTF-8 formatted, so as with other
places in this module, try latin-1 if utf-8 fails.

This fixes UnicodeDecodeError running devtool update-recipe or devtool
finish on the openssl recipe.
