Check the correct length of the GPT header signature

The length of the signature is 8 bytes. We've been checking 9
bytes instead, pretty much forever. All the tests have passed
because although the signature we're looking for is an 8-byte
string followed by a '\0', the next field in the header contains
the revision number 0x00010000, so the 9th byte is always zero.

We should follow the spec, though.
