Merge branch 'rj/submodule-fsck-skip'

"fsck.skipList" did not prevent a blob object listed there from
being inspected for is contents (e.g. we recently started to
inspect the contents of ".gitmodules" for certain malicious
patterns), which has been corrected.

* rj/submodule-fsck-skip:
  fsck: check skiplist for object in fsck_blob()
