[PATCH 20/23] fsck: rename vague "oid" local variables

[Jeff King <peff@peff.net>]

In fsck_commit() and fsck_tag(), we have local "oid" variables used for
parsing parent and tagged-object oids. Let's give these more specific
names in preparation for the functions taking an "oid" parameter for the
object we're checking.
