fsck: add stress tests for fsck.skipList

Stress test the parsing logic shared by fsck.skipList and
{fetch,receive}.fsck.skipList added in cd94c6f91e ("fsck: git
receive-pack: support excluding objects from fsck'ing",
2015-06-22). There were no tests for the work done by the
init_skiplist() routine, e.g. how it dies on invalid input.
