lib: Add crc32c function that can deal with holes

XFS, and possibly other filesystems expect that the CRC field
is excluded (or rather RAZ) during the CRC operation. Lets
create a generic helper that is similar to the CRC32 version
ul_crc32_exclude_offset() which computes the CRC while replacing
exclude_len bytes of exclude_off with zeros.
