Jeff King 34959d80db t: use hash-object --literally when created malformed objects
Many test scripts use hash-object to create malformed objects to see how
we handle the results in various commands. In some cases we already have
to use "hash-object --literally", because it does some rudimentary
quality checks. But let's use "--literally" more consistently to
future-proof these tests against hash-object learning to be more
careful.
