Title: Fixed PHP-622: MinKey is not deserialized properly on 32bit big-endian devices

On the 32-bit big-endian ARM architecture that the Raspberry Pi uses, the use
of -1 for an unsigned char is incorrect. The specification at
http://bsonspec.org/#/specification says that MinKey is supposed to be 0xFF,
and hence I am making this change.
