buffer: bugfix (v3) fix the checksum

The BIOS is expected to use the XOR checksum which behaves ever so
slightly different compared to summing up the bytes (even though
bitwise XOR is the same as addition).

Fixed the unit test accordingly

Tested: Unit test + tested on a BIOS with real / valid checksummed
payload
