csum-file: store the hash algorithm as a struct field
Throughout the hashfile API, we rely on a reference to 'the_hash_algo',
and call its _unsafe function variants directly.
Prepare for a future change where we may use a different 'git_hash_algo'
pointer (instead of just relying on 'the_hash_algo' throughout) by
making the 'git_hash_algo' pointer a member of the 'hashfile' structure
itself.
