[PATCH v2 08/21] fsck: convert init_skiplist to struct object_id

[brian m. carlson]

Convert a hardcoded constant buffer size to a use of GIT_MAX_HEXSZ, and
use parse_oid_hex to reduce the dependency on the size of the hash.
This function is a caller of sha1_array_append, which will be converted
later.
