lib/crc32: don't require to modify GPT header

This patch introduces smart crc32 function that is able to exclude
specified. The advantage is that we does not have to modify GPT header
(set the current in-header crc field to zero) when we count crc32.

This allows to keep GPT header in read-only buffers and simplify code.
